Bit Name
Default
Bit No.
Type
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 RSCK to update the data on RSD and RSIG and the active edge of MRSCK to update the data on MRSD and
= 0: The falling edge is selected.
= 1: The rising edge is selected.
This bit selects the active edge of RSCK to update/sample the pulse on RSFS and the active edge of MRSCK to sample the pulse on MRSFS.
= 0: The falling edge is selected.
= 1: The rising edge is selected.
This bit is valid in Receive Clock Slave T1/J1 mode E1 rate and Receive Multiplexed mode.
= 0: The speed of the RSCK/MRSCK is the same as the data rate on the system side (2.048 MHz / 8.192 MHz).
= 1: The speed of the RSCK/MRSCK is double the data rate on the system side (4.096 MHz / 16.384 MHz).
= 0: The processed data and signaling bits are output on the RSD/MRSD pins and the RSIG/MRSIG pins respectively.
= 1: The output on the RSD/MRSD pins and the RSIG/MRSIG pins are in high impedance.
