== Synopsis ==
'''Port Number:''' 11h

'''Function:''' LCD Data Port

This port transfers data to and from the LCD driver's internal RAM.

=== Read Values ===
* The byte at the current location in RAM. Each bit corresponds to one pixel.

=== Write Values ===
* Sets the byte at the current RAM location. Each bit corresponds to one pixel.

== Comments ==
In 6-bit word mode only bits 0~5 have any significance.

THe RAM location affected can be changed through the [[83Plus:Ports:10|command port]]. The location will also automatically change according to the auto-increment or auto-decrement mode as set in the command port. As with sending commands, you must wait a full LCD Cycle (10 microseconds) between reads and writes.

== Example ==
<nowiki>;Cause all the pixels at the current location to be black.
ld a, 0FFh
out (11h), a
push hl
push de
pop de
pop hl
nop
;And turn them back off.
xor a
out (11h), a</nowiki>
