Espial memory map (preliminary)
MAIN CPU:
0000-4fff ROM
5800-5fff RAM
8000-800f sprites code (bits 1-7) and double height (bit 0)
8010-801f sprites X
8400-87ff Video RAM
8800-880f sprites flip x (bit 2) and flip y (bit 3)
8c00-8fff Attribute RAM
9000-900f sprites Y
9010-901f sprites color
9020-903f column scroll
9400-97ff Color RAM
c000-cfff ROM
read:
6081 IN0
6082 IN1
6083 IN2
6084 IN3
6090 read command back from sound CPU
7000 ?
write:
6081 ? - written to twice when the text during the self-test is drawn onscreen
6090 write command to sound CPU
7000 watchdog reset
7100 NMI interrupt acknowledge/enable
7200 flip screen
Interrupts: VBlank -> NMI.
IRQ -> send sound commands to sound cpu. Runs in interrupt mode 1
SOUND CPU:
0000-1fff ROM
2000-23ff RAM
read:
6000 read command from main CPU
write:
4000 NMI enable
6000 write command back to main CPU
Interrupts: IRQs are triggered by writes to the sound_command location 0x6000 - im 1
NMIs occur regularly to process and play the sounds
I/0 ports:
write
00 8910 control
01 8910 write
