Registers addresses
3.1.27
3.1.28
36/51
Interrupt register (INT)
Addr=21h; Reset Value=00h
ICKF = 1: If interrupt is generated by a change of bit 0 in register ALARM.
In dynamic I/O configuration the ID3..0 bits latch the interrupt request from the related
channel.
Any single bit IDn is cleared after reading related I/O register or by setting MCn bit High (i.e.
when channel n is disabled to generate interrupt).
In static I/O configuration ID0 and ID2 bits latch the interrupt request from I/O11..0 and
CS3..0 respectively:
ID0: is set High when the interrupt is requested from any the I/O11..0 lines.
ID2: is set High when the interrupt is requested from any of the CS3..0 (configured as I/O).
ID0 and ID2 are cleared after reading related I/O register.
ID1 and ID3 are don’t care.
Pin-strap value (value=00b):
Alarm register (ALARM)
Addr=22h; Reset Value=00h
CKF=1: If number of PCM clock pulses in one frame period does not match expected value.
POR=1: If a Power On Reset is detected during operation.
The register ALARM is cleared after reading operation only if signals are inactive.
Pin-strap value (value=00h):
