STA1M - Status 1 Mask Register - (write 8Dh)
If any following bit is enabled, the flag STAERR (80h.r6) becomes high when the corresponding
status bit becomes active.
Bit 4: HDERA Mask
Bit 0: SHDER Mask
STA2M - Status 2 Mask Register - (write 8Eh)
If any following bit is enabled, the flag STAERR (80h.r6) becomes high when the corresponding
status bit becomes active.
Bit 2: NOCOR Mask
Bit 1: RFOMR1 Mask
STA3M - Status 3 Mask Register - (write 8Fh)
If any following bit is enabled, the flag STAERR (80h.r6) becomes high when the corresponding
status bit becomes active.
Bit 5: CBLK Mask
Bit 4: ECCINC Mask
Bit 1: C2BLK Mask
APCNF - Audio Playback Configuration Register - (read/write 90h)
The default value of this register is 00h after chip reset, host reset and firmware reset.
Bit 7: APEN - Audio Playback Enable
Setting this bit high enables audio playback logic. Once audio playback logic is enabled, the
buffered data will be sent out block after block starting from the setting of APBK (92h/93h).
The playback stops immediately and keeps "mute" once this bit is set low.
Bit 6: APIEN - Audio Playback Interrupt Enable
Setting this bit high enables audio-playback-interrupt to be reflected on pin UINTb (36)
whenever each block playback is finished. Audio-playback-interrupt flag is reflected on APIb
(01h.r2) if APOUT1-0 (90h,1-0) is not zero.
