= Quick Specs =
* ILI9335
* TFT color LCD
* Supports 8 and 16-bit interfaces
* 172,800 bytes internal RAM
* 76,800 pixels
* Power-saving 8-color mode
* 262,144 = 2^18 = 6x6x6 colors
* Data sheet: http://www.displayfuture.com/Display/datasheet/controller/ILI9335.pdf

= Overview =

Like the old LCD controller, the new color controller is controlled by ports
10h and 11h. The LCD controller wants 16- or 18-bit data, but the Z80 only does
8-bit I/O, so each read or write takes TWO operations. The controller expects
them to be in big-endian order, i.e. to output 1234h, you write 12h first, then
write 34h to the SAME port. Writes to port 10h set the current "register".
You need to send 16-bits to 10h at a time, even though there are no registers
above 0FFh; every time you set the current register, send a dummy zero first, or alternatively, send the same byte twice.
Reading 10h probably returns some kind of status information (more information
needed). Reading and writing to 11h reads or writes to or from a register.

Therefore, to send the LCD a command, you first send two bytes to port 10h
to set the current register. Then, you send two bytes to write the data.
Similarly, to read, write the register number to 10h, and then read twice from
11h. You should be able to read-modify-write without resending the register
number.

To send graphics to the LCD, set the column and row address
registers, and then send the data serially to register #22h. You do not need to
write 00 22h to port 10h after every byte.

NOTA BENE: IMPORTANT TERMINOLOGY:

In this document, the word "cursor" refers to the LCD controller's current
reading or writing location on the screen; that is, the current row and column
set by registers 20h and 21h.

(For those following along with the data sheet:
Like before, the X/Y plane is flipped in the data sheet documentation.
Specifically, the the screen is rotated 90 degrees from the way the manufacturer
expects, so "horizontal" and "vertical" refer to the OTHER, i.e. horizontal
means up and down on the screen. Also, "up" and "down" are switched with "left"
and "right". Also, the auto-increment behavior in hardware is rotated 90
degrees clockwise from the register 0x03 diagram. It also suggests that the
manufacturer expects the screen to be in landscape mode, which is wrong.)

To resolve potential CONFUSION about the meaning of the words "horizontal",
"vertical", "up", "down", "left", "right", "X", and "Y", (see above paragraph)
this document will use the terms "row" and "Y" to refer to the up/down direction
positioning of the cursor on the actual calculator; similarly, "column" and "X"
refer to the left/right axis. Additionally, as is standard for computer
screens, the X=0 position is at the left side, and X+ is pointing to the right;
and moreover, Y=0 is at the top, and Y+ points DOWN.

READ THE ABOVE OR YOU WILL HAVE BUGS!

Like the old B&W LCD controller, this one has an internal cursor (the
data sheet calls it the GRAM address) that determines where data written or read
goes. Unlike the old controller, setting the row register will cause the column
pointer to reset to the last value written, and vice versa. For example, if you
set the row to 1, the column to 2, write a pixel so the column is now 3, and
then set the row to 5, the column will not remain at 3, but revert to 2. (If
you then set the column to 10, the row remains at 5, because 5 is the last value
you wrote.)

So, port 10h:
* Writing sets the index for the IR register
* Reading reads an internal status code
* Write four zeros to sync for multibyte transfers
Port 11h:
* Writing sets a control register value or writes to GRAM (auto-buffered to WRD)
* Reading reads from GRAM through the buffered RDR register (so a dummy
read (16-bits!) is required before the data are valid, just like
before)

TI always uses the 16-bit color mode, and they always set BGR color order,
for no good reason.

If you read the data sheet, the interface mode is the I80 8-bit mode.

=== Windows ===

To make life a little less terrible, the LCD controller supports setting a "window" into which the cursor is confined. In this window, if moving to the next pixel---whichever direction that may be---would move the cursor outside the bounds of the window, the cursor will instead move to the start of the next appropriate row or column, as determined by the entry mode, eventually wrapping back to the start of the window. This makes it easier to write sprites and do tiny animations. Windowing is always active, so it's something you must keep track of. Furthermore, you ''must'' set the cursor to inside the window when you change it, or else the screen will go totally wonky and display garbage when you try to write pixels to it.

=== Partial Image Mode ===

This has the potential to be quite useful. In particular, it allows a hacked 160x240 mode in which each pixel is twice as wide as normal. Somebody should probably add more information on this.

=== Panic Mode ===

If you do something the LCD controller finds particularly adverse (like set the cursor to be outside of the window bounds and try to write pixels), the LCD controller will display garbage lines everywhere. It will not operate normally again until you perform the power-off and power-on sequences.

== Power Control ==

The B&W screen can be initialized with just half-a-dozen writes. The color screen is much more complicated. Power-on and power-off both require many writes with minimum wait times.

Be aware! The LCD controller is not connected to the LCD backlight controller. They are separate hardware, and operate independently. The LCD controller can be on without the backlight being on (you can't see anything except if you shine a very, very bright light directly on the screen), and the backlight can be on with LCD controller off. Port 3A controls the LCD backlight (among other things).

= Register List =

This is a list of all the LCD's registers, what each bit does (if anything),
and the values the OS expects for normal operation, so you can hopefully return
the screen to normal after you're done screwing things up.

You should probably not screw with the power and scanning control registers.
The screen might catch on fire, or cause the screen to fade over time, or just
stop working.
Remember, some of said registers directly control the internal voltages used in the controller.

|AM: Cursor direction. Set = L/R, reset = U/D. After every pixel, the cursor moves either U/D or L/R.
If set to L/R (1), after every pixel the cursor moves left
(bit 5=0) or right (b5=1). At the end of the row, the cursor
moves up (b4=0) or down (b4=1).

If AM is set to U/D, after every pixel, the cursor moves up
(b4=0) or down (b4=1). At the end of each column, the cursor
moves left (b5=0) or right (b5=1).

At the end of every row or column, the cursor resets to the
start of the next line, where ever the current window setting
puts it.

|ORG: The controller's wording suggests that if this is set, then the cursor seeks to the corner of the window when the window is set, but this appears to be wrong?
|-

|1
|BGR: If this is set, the "red" and "blue" channels are swapped both when writing pixels to GRAM, and when reading pixels from GRAM. Note that this doesn't affect the appearance of existing pixels.
|-
|14
|0
|TRI: If set, 3 writes are required for every pixel (of which 18 bits are used, allowing up to 218 distinct colors to be displayed.) Note that unlike the BGR bit, TRI only affects output operations, not input operations.
|-
|15
|0
|DFM: If reset, the 3 writes are packed.
If set, the 3 writes are unpacked. (That is, write 1 byte red,
1 byte green, and finally 1 byte blue, or reverse for BGR.)
|}
The display has three color modes:
{|-
|TRI   
|DFM   
|Transfer Mode
|-
|0
|any
|16-bit color, packed values, MSB first (big endian)
|-
|1
|0
|18-bit color, packed values, R[5:4] low bits of first transfer
|-
|1
|1
|18-bit color, unpacked values, uses high 6 bits, low two bits
ignored
|}

For example, to draw an orange pixel (R=100%, G=50%, B=0%) in TRI=0/BGR=1 mode, you would write 11111011b, 11100000b. In TRI=1/DFM=0/BGR=1 mode, you would write 00000011b, 11110111b, 11000000b. In TRI=1/DFM=1/BGR=1 mode, you would write 11111100b, 01111100b, 00000000b.

=== 05: 16-bit Data Format Selection ===
The ILI9335 documentation is wrong about this register. It claims that it controls how the least-significant bits of the red and blue channels are determined when TRI=0. Experiments, however, have shown that the mode described as "EPF=10" is always used, regardless of the value of R05. In this mode, the most significant bit is copied into the least significant bit - or in other words, the input values are multiplied by 63/31 and rounded to the nearest integer.

(For reference, the documentation claims that mode 00 sets the least significant bits to 0; mode 01 sets the least significant bits to 1; mode 10 does as described above; and mode 11 does something not-completely-explained based on whether the red and blue values are equal.)

If this register has any effect, it's unknown.

=== 20: Cursor Row ===
The datasheet calls this the "Horizontal GRAM Address" , but it sets the up/down position of the cursor because the
display is on its side.

Sets the left/right position of the cursor.
NOTA BENE: Setting one register will cause the other to revert
to its previous value; see Overview, above.

=== 22: GRAM ===
This is the register that you use to actually send and read pixels.

When reading, a dummy read is required before a cursor change
takes effect; i.e., after writing 20 and 21, do a 16-bit
dummy read before saving the actual data.

Reading does not appear to update the cursor, so you can do a read-modify-write type operation, which might be useful for masking or implementing gratuitous transparency effects.
