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
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
