Bit No.
These bits select the operation mode in the receive path.
‘Receive Clock Master Full T1/J1’ mode means that the received entire frame (193 bits) is clocked out from the RSDn pin, and there are no gaps
‘Receive Clock Master Fractional T1/J1’ mode means that RSCKn only clocks out on the selected channels, and RSCKn does not pulse during

When Receive Clock Slave External Signaling mode is enabled, the RSCKn/RSSIGn pin is used as RSSIGn to output the extracted signaling
When Receive Clock Slave RSCK Reference Mode is enabled, this bit selects the frequency of RSCKn.
= 0: RSCKn outputs an 8 KHz timing reference that is generated by dividing the jitter attenuated version of LRCKn.
= 1: RSCKn outputs a jitter attenuated version of the 1.544MHz receive line clock (LRCK).
These bits determine the bit rate of the received data stream on the backplane. The 2.048 Mbit/s rate can only be supported when the backplane
