80000d byte Page register. One bit means one uncovered page sensor.
00 - storyware closed
01, 03, 07, 0f, 1f, 3f - pages 1-6
either page 5 or page 6 is often unused.
800010 word PCM data register.
r/w read returns free bytes left in PCM FIFO buffer
writes write data to buffer.
800012 word PCM control register.
r/w For writes, it has following possible meanings:
?p?? ???? ???? ?rrr
p - set to enable playback?
r - sample rate / PCM data type?
0: 8kHz 4bit ADPCM?
1-7: 16kHz variants?
For reads, if bit 15 is cleared, it means PCM is 'busy' or
something like that, as games sometimes wait for it to become 1.
800019 byte Games write 'S'
80001b byte Games write 'E'
80001d byte Games write 'G'
80001f byte Games write 'A'
