The PCM receive path cutoff bit (CUTOFF) is used to cut off the PCM receive path.
CUTOFF = 0:
CUTOFF = 1:
The SLIC Input Interrupt Enable bits (IE[3:0]) enable or disable the interrupt signal on the corresponding channel.
IE[0] = 0:
IE[0] = 1:
IE[1] = 0:
IE[1] = 1:

Loopback Control, Read/Write (02H/82H)
The loopback control bit ALB_PCM determines the status of the loopback ALB_PCM on the corresponding channel.
ALB_PCM = 0: The analog loopback via the PCM interface on the corresponding channel is disabled (default);
ALB_PCM = 1: The analog loopback via the PCM interface on the corresponding channel is enabled.
DSH Debounce and GK Debounce Configurations, Read/Write (03H/83H)
The DSH Debounce bits (DSH[3:0]) is used to set the debounce time for the SI1 input of the corresponding channel. The debounce time
for SI1 is programmable from 0 to 30 ms in step of 2 ms.
DSH[3:0] = 0000: 0 ms (default);
DSH[3:0] = 0001: 2 ms;
DSH[3:0] = 0010: 4 ms;
DSH[3:0] = 0011: 6 ms;
DSH[3:0] = 0100: 8 ms;
DSH[3:0] = 0101: 10 ms;
DSH[3:0] = 0110: 12 ms;
DSH[3:0] = 0111: 14 ms;
DSH[3:0] = 1000: 16 ms;
DSH[3:0] = 1001: 18 ms;
DSH[3:0] = 1010: 20 ms;
DSH[3:0] = 1011: 22 ms;
DSH[3:0] = 1100: 24 ms;
DSH[3:0] = 1101: 26 ms;
DSH[3:0] = 1110: 28 ms;
DSH[3:0] = 1111: 30 ms.
The GK Debounce bits (GK[3:0]) is used to set the debounce interval for the SI2 input of the corresponding channel. The debounce time

The PCM receive path in normal operation;
The PCM receive path is cut off.
Interrupt disable. The interrupt signal generated by the SB2 pin of the corresponding channel (when the SB1 pin is
configured as an input) will be ignored (default);
Interrupt enable. The interrupt signal generated by the SB2 pin of the corresponding channel (when the SB1 pin is
configured as an input) will be recognized;
