The PCM data Offset Configuration bits (OC[2:0]) determine that the transmit and receive time slots of PCM data offset from the FS
signal by how many periods of BCLK:
OC[2:0] = 000:
OC[2:0] = 001:
OC[2:0] = 010:
OC[2:0] = 011:
OC[2:0] = 100:
OC[2:0] = 101:
OC[2:0] = 110:
OC[2:0] = 111:
The Output Polarity Indicator bit (OPI) indicates the valid polarity of output:
OPI = 0:
OPI = 1:
The Input Polarity Indicator bit (IPI) indicates the valid polarity of input:
IPI = 0:
IPI = 1:
The Input Selection bit (IS) determines which input will be selected as the off-hook indication signal source.
IS = 0:
IS = 1:
The Ring Trip Enable bit (RTE) enables or disables the ring trip function block:
RTE = 0:
RTE = 1:
The Output Selection bits (OS[2:0]) determine which output will be selected as the ring control signal source.
OS[2:0] = 000 - 010:
OS[2:0] = 011:
OS[2:0] = 100:
OS[2:0] = 101:
OS[2:0] = 110:
OS[2:0] = 111:
The SIA[3:0] bits contain the debounced data (off-hook status) on the SI1 pins of Channel 4 to Channel 1 respectively.
The SIB[3:0] bits contain the debounced data (ground key status) on the SI2 pins of Channel 4 to Channel 1 respectively.
