CS8416
INT[1:0] - Interrupt output pin (INT) control
Default = 鈥?0鈥?/div>
00 - Active high; high output indicates interrupt condition has occurred
01 - Active low, low output indicates an interrupt condition has occurred
10 - Open drain, active low. Requires an external pull-up resistor on the INT pin. Thus it is not recom-
mended to multiplex INT onto GPO2 in I
2
C control port mode since an external resistor is re-
quired on GPO2 to specify the AD2 bit of the chip address.

100 鈥?50us/15us de-emphasis filter auto-select on. Coefficients(32, 44.1 or 48 KHz or no de-empha-
sis filter at all) match the pre-emphasis and sample frequency indicators in the channel status bits of
Channel A. Thus it is impossible to have de-emphasis applied to one channel but not the other. Also
it turns off the de-emphasis filter if the audio data is detected to be non-linear data.
