Programming Information
Bit Name
Default
Bit No.
Type
This bit is valid in Transmit 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 TSCKn to sample the data on TSDn and TSIGn and the active edge of MTSCK to sample the data on MTSDA
= 0: The falling edge is selected.
= 1: The rising edge is selected.
In Transmit Multiplexed mode, the bit of the four links should be set to the same value.
This bit selects the active edge of TSCKn to update/sample the pulse on TSFSn and the active edge of MTSCK to sample the pulse on MTSFS.
= 0: The falling edge is selected.
= 1: The rising edge is selected.
In Transmit Multiplexed mode, the bit of the four links should be set to the same value.
This bit is valid in Transmit Clock Slave T1/J1 mode E1 rate and Transmit Multiplexed mode.
= 0: The speed of the TSCKn / MTSCK is the same as the data rate on the system side (2.048 MHz / 8.192 MHz).
= 1: The speed of the TSCKn / MTSCK is double the data rate on the system side (4.096 MHz / 16.384 MHz).
In Transmit Clock Slave T1/J1 mode E1 rate, if all four links use the TSCK[1] and TSFS[1] to input the data (i.e., the TSLVCK bit (b, T1/J1-010H)
In Transmit Multiplexed mode, the bit of the four links should be set to the same value.
= 0: The transmit framing pulse TSFSn is active high.
= 1: The transmit framing pulse TSFSn is active low.
In Transmit Multiplexed mode, this bit of the four links should be set to the same value.
= 0: In Transmit Non-multiplexed mode, TSFSn pulses during each F-bit. In Transmit Multiplexed mode, MTSFS pulses during each F-bit of the
= 1: In Transmit Non-multiplexed mode, TSFSn pulses during the first F-bit of every SF/ESF/T1 DM/SLC-96 frame. In Transmit Multiplexed
In Transmit Multiplexed mode, this bit of the four links should be set to the same value.
