IDT821054 QUAD PROGRAMMABLE PCM CODEC WITH MPI INTERFACE
INDUSTRIAL TEMPERATURE RANGE
IE[0] = 1: Interrupt enabled. The interrupt generated by changes of SI1 will be recognized.
The Loopback Control Bits (DLB_PCM, ALB_1BIT and DLB_1BIT) determine the loopback status on the corresponding channel. Refer
to Figure - 4 on page 11 for details.
DLB_PCM = 0: Digital Loopback via Time Slots on the corresponding channel is disabled (default);
DLB_PCM = 1: Digital Loopback via Time Slots on the corresponding channel is enabled.
ALB_1BIT = 0: Analog Loopback via Onebit on the corresponding channel is disabled (default);
ALB_1BIT = 1: Analog Loopback via Onebit on the corresponding channel is enabled;
DLB_1BIT = 0: Digital Loopback via Onebit on the corresponding channel is disabled (default);
DLB_1BIT = 1: Digital loopback via Onebit on the corresponding channel is enabled;
LREG3: DSH and GK Debounce Filters Configuration, Read/Write (02H/82H)
The DSH Debounce bits DSH[3:0] are used to set the debounce time of SI1 input of the corresponding channel.
DSH[3:0] = 0000: The debounce time is 0 ms (default);
DSH[3:0] = 0001: The debounce time is 2 ms;
DSH[3:0] = 0010: The debounce time is 4 ms;
DSH[3:0] = 0011: The debounce time is 6 ms;
DSH[3:0] = 0100: The debounce time is 8 ms;
DSH[3:0] = 0101: The debounce time is 10 ms;
DSH[3:0] = 0110: The debounce time is 12 ms;
DSH[3:0] = 0111: The debounce time is 14 ms;
DSH[3:0] = 1000: The debounce time is 16 ms;
DSH[3:0] = 1001: The debounce time is 18 ms;
DSH[3:0] = 1010: The debounce time is 20 ms;
DSH[3:0] = 1011: The debounce time is 22 ms;
DSH[3:0] = 1100: The debounce time is 24 ms;
DSH[3:0] = 1101: The debounce time is 26 ms;
DSH[3:0] = 1110: The debounce time is 28 ms;
DSH[3:0] = 1111: The debounce time is 30 ms.
The GK Debounce bits GK[3:0] are used to set the debounce interval of SI2 input of the corresponding channel. The debounce interval is
programmable from 0 to 30 ms, corresponding to the minimal debounce time of 0 to 180 ms.
GK[3:0] = 0000: The debounce interval is 0 ms (default);
GK[3:0] = 0001: The debounce interval is 2 ms;
GK[3:0] = 0010: The debounce interval is 4 ms;
GK[3:0] = 0011: The debounce interval is 6 ms;
GK[3:0] = 0100: The debounce interval is 8 ms;
GK[3:0] = 0101: The debounce interval is 10 ms;
GK[3:0] = 0110: The debounce interval is 12 ms;
GK[3:0] = 0111: The debounce interval is 14 ms;
GK[3:0] = 1000: The debounce interval is 16 ms;
GK[3:0] = 1001: The debounce interval is 18 ms;
GK[3:0] = 1010: The debounce interval is 20 ms;
GK[3:0] = 1011: The debounce interval is 22 ms;
GK[3:0] = 1100: The debounce interval is 24 ms;
GK[3:0] = 1101: The debounce interval is 26 ms;
GK[3:0] = 1110: The debounce interval is 28 ms;
GK[3:0] = 1111: The debounce interval is 30 ms;
