New page

'''Note:''' Do not take the information on this template page as actual documentation!

The Ports are named by their number, in hexadecimal. An example is [[83Plus:Ports:00]].

You also must put a variation on the following code into your page to have it categorized:
NaodW29-nowiki524ead3d48187e5400000001

== Synopsis ==
'''Port Number:''' 06h

'''Function:''' Flash Memory Paging

This port controls what page is swapped into the 4000h to 7FFFh range. ('''DO NOT''' take this template page as real documentation on port 6!)

=== Read Values ===
* [00h - FFh]: The current port mapped to the memory range 4000h through 7FFFh.

=== Write Values ===
* [00h - FFh]: The new page to swap in to the memory range 4000h through 7FFFh

''Note: if you would have bitwise flags for your port, label them "bit X".''

== Comments ==
The behavior of this port changes in different memory map modes.

== Example ==

== Credits and Contributions ==
* '''/dev/urandom:''' Because of your randomness, this project is possible.

 === Write Values ===
-''None''
+Writing to this port sets the signaling rate of the link assist in CPU speed mode 0 (6 MHz); the link assist uses the same clock as the CPU. Bits 5 through 7 control a divisor to the clock before it reaches the link assist, affecting how fast the link assist can detect changes in the signal states. It will divide by 2^n, allowing you to divide by 1, 2, 4 ... 64. Value 111b (7) will halt the link assist. Bits 0 through 4 control how much time to wait between bits. TI desires a minimum time between bits of 2 microseconds.
