Bits 0 to 7/Software Signaling Insertion Enable for and Channels 1 to 8 (CH1 to CH8 ). These bits determine what
channels are to have signaling inserted form the transmit signaling registers.
0 = do not source signaling data from the TSx registers for this channel
1 = source signaling data from the TSx registers for this channel
