CONF_CS[1:0] = 01: Channel 2 is selected;
CONF_CS[1:0] = 10: Channel 3 is selected;
CONF_CS[1:0] = 11: Channel 4 is selected.
Gain = G_CONF[7:0] / 256
The default value of G_CONG[7:0] bits is 0(d).
Transmit PCM highway selection for part B in three-party conference
THS_B = 0:
THS_B = 1:
Transmit time slot selection for part B in three-party conference.
The valid value of the TT_B[6:0] bits is from 0(d) to 127(d), corresponding to Time Slot 0 to Time Slot 127.
The default value of TT_B[6:0] is 0(d).
RHS_B
Receive PCM highway selection for part B in three-party conference
RHS_B = 0:
RHS_B = 1:
Receive PCM time slot selection for part B in three-party conference.
The valid value of the RT_B[6:0] bits is from 0(d) to 127(d), corresponding to Time Slot 0 to Time Slot 127.
The default value of RT_B[6:0] is 0(d).
Transmit PCM highway selection for part C in three-party conference
THS_C = 0:
THS_C = 1:
Transmit time slot selection for part C in three-party conference.
The valid value of the TT_C[6:0] bits is from 0(d) to 127(d), corresponding to Time Slot 0 to Time Slot 127.
The default value of TT_C[6:0] is 0(d).
