INT[1:0] - Interrupt output pin (INT) control

Default = ‘00’

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 I2C control port mode since an external resistor is re-

quired on GPO2 to specify the AD2 bit of the chip address.

11 – Reserved

CHS – Sets which channel's C data is decoded in the Receiver Channel Status register

0 – A channel

1 – B channel

DETCI – D to E status transfer inhibit

Default = ‘0’

0 – Allow update

1 – Inhibit update

Emph_CNTL[2:0] – De-emphasis filter control

Default = 000

000 – De-emphasis filter off

001 – 32 KHz setting

010 – 44.1 KHz setting

011 – 48 KHz

100 – 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.

GPO0SEL[3:0] – GPO0 Source select. See GPO section in main text for settings table.

Default = 0000
