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 TSCK to sample the data on TSD and TSIG and the active edge of MTSCK to sample the data on MTSD and
= 0: The falling edge is selected.
= 1: The rising edge is selected.
This bit selects the active edge of TSCK to update/sample the pulse on TSFS and the active edge of MTSCK to sample the pulse on MTSFS.
= 0: The falling edge is selected.
= 1: The rising edge is selected.
This bit is valid in Transmit Clock Slave T1/J1 mode E1 rate and Transmit Multiplexed mode.
= 0: The speed of the TSCK / MTSCK is the same as the data rate on the system side (2.048 MHz / 8.192 MHz).
= 1: The speed of the TSCK / MTSCK is double the data rate on the system side (4.096 MHz / 16.384 MHz).
= 0: The transmit framing pulse TSFS is active high.
= 1: The transmit framing pulse TSFS is active low.
= 0: In Transmit Non-multiplexed mode, TSFS pulses during each F-bit. In Transmit Multiplexed mode, MTSFS pulses during each F-bit.
= 1: In Transmit Non-multiplexed mode, TSFS pulses during the first F-bit of every SF/ESF/T1 DM/SLC-96 frame. In Transmit Multiplexed mode,
