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-nowiki605b15f223c35f2d00000001

----

== 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 ==
NaodW29-nowiki605b15f223c35f2d00000002

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