Programming Information
Bit Name
Default
Bit No.
Type
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 MRSD
= 0: The falling edge is selected.
= 1: The rising edge is selected.
In Receive Multiplexed mode, the bit of the two 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 two links should be set to the same value.
This bit is valid in Receive Clock Slave mode and Receive Multiplexed mode.
= 0: The speed of RSCKn/MRSCK is the same as the data rate on the system side (2.048 Mb/s / 8.192 Mb/s).
= 1: The speed of RSCKn/MRSCK is double the data rate on the system side (4.096 Mb/s / 16.384 Mb/s).
In Receive Clock Slave mode, if both two links use the RSCK[1] and RSFS[1] to output the data (i.e., the RSLVCK bit (b, E1-01H) is set to ‘1’), the
In Receive Multiplexed mode, the bit of the two links should be set to the same value.
= 0: The processed data and signaling bits are output on the RSDn/MRSD and RSIGn/MRSIG pins respectively.
= 1: The output on the RSDn/MRSD and RSIGn/MRSIG pins are in high impedance.
