3. Teletax Gain Setting (02H/82H), Read/Write
gain is 0, ‘FFH’ represents the gain of 1. There are totally 255 steps between gain 0 and 1 corresponding to the value of the command I/O data.
4. DSH Debounce and GK Debounce (03H/83H), Read/Write
IDT821068 OCTAL PROGRAMMABLE PCM CODEC
Teletax Gain Setting bits (TGS[7:0]) are used to set the gain of teletax on corresponding channel. The default value is ‘00H’ which means the
DSH Debounce bits (DSH[3:0]) set the debounce time of SI1 input from SLIC on corresponding channel.
GK Debounce bits (GK[3:0]) set the debounce interval of SI2 input from SLIC on corresponding channel.
