Transmit PCM highway selection for the specified channel.
THS = 0:
THS = 1:
Transmit time slot selection for the specified channel.
The valid value of the TT[6:0] bits is from 0(d) to 127(d), corresponding to Time Slot 0 to Time Slot 127.
The default value of TT[6:0] is 00H for Channel 1, 01H for Channel 2, 02H for Channel 3 and 03H for Channel 4.
Receive PCM highway selection for the specified channel.
RHS = 0:
RHS = 1:
Receive time slot selection for the specified channel.
The valid value of the RT[6:0] bits is from 0(d) to 127(d), corresponding to Time Slot 0 to Time Slot 127.
The default value of RT[6:0] is 00H for Channel 1, 01H for Channel 2, 02H for Channel 3 and 03H for Channel 4.
