New page

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

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 ==
<nowiki>push af
in a,(6)
ld (oldMemPage),a
ld a,1
out (6),a
; do stuff that needs page 1 swapped in
ld a,(oldMemPage)
out (6),a
pop af</nowiki>
