Bit Name
This bit is valid in Receive Clock Master mode.
= 0: The F-bit is not gapped.
= 1: The F-bit is gapped (no clock signal during the F-bit).
This bit selects the active edge of RSCKn to update the data on RSDn and RSIGn and the active edge of MRSCK to update the data on MRSDA
= 0: The falling edge is selected.
= 1: The rising edge is selected.
In Receive Multiplexed mode, the bit of the eight links should be set to the same value.
This bit selects the active edge of RSCKn to update/sample the pulse on RSFSn and the active edge of MRSCK to sample the pulse on MRSFS.
= 0: The falling edge is selected.
= 1: The rising edge is selected.
In Receive Multiplexed mode, the bit of the eight links should be set to the same value.
This bit is valid in Receive Clock Slave T1/J1 mode E1 rate and Receive Multiplexed mode.
= 0: The speed of the RSCKn/MRSCK is the same as the data rate on the system side (2.048 MHz / 8.192 MHz).
= 1: The speed of the RSCKn/MRSCK is double the data rate on the system side (4.096 MHz / 16.384 MHz).
In Receive Clock Slave T1/J1 mode E1 rate, if all eight links use the RSCK[1] and RSFS[1] to output the data (i.e., the RSLVCK bit (b, T1/J1-010H)
In Receive Multiplexed mode, the bit of the eight links should be set to the same value.
= 0: The processed data and signaling bits are output on the RSDn/MRSDA(MRSDB) pins and the RSIGn/MRSIGA(MRSIGB) pins respectively.
= 1: The output on the RSDn/MRSDA(MRSDB) pins and the RSIGn/MRSIGA(MRSIGB) pins are in high impedance.
