Remote Loopback
Setting this bit activates the remote loopback function. The received 2B channels from the S
interface are looped to the transmitted 2B channels of S/T interface. The D channel is not
looped in this loopback function.
This bit remains set, until cleared by software reset (SRST).
These two bits select the output phase delay compensation.
