ing the first bit of each Basic frame.
the Signaling Multi-frame is to be generated, TSFSn pulses during the first bit of each Signaling Multi-frame; if both the CRC Multi-frame and the Sig-
naling Multi-frame are to be generated, TSFSn goes high/low during the first bit of each Signaling Multi-frame and goes the opposite during the sec-
ond bit of each CRC Multi-frame. In Transmit Multiplexed mode, if the CRC Multi-frame is to be generated, MTSFS pulses during the first bit of each
CRC Multi-frame; if the Signaling Multi-frame is to be generated, MTSFS pulses during the first bit of each Signaling Multi-frame; if both the CRC Multi-
frame and the Signaling Multi-frame are to be generated, MTSFS goes high/low during the first bit of each Signaling Multi-frame and goes the opposite
during the second bit of each CRC Multi-frame.

Bit Name
Default
Bit No.
Type
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 mode and Transmit Multiplexed mode.
= 0: The speed of TSCK/MTSCK is the same as the data rate on the system side (2.048 Mb/s / 8.192 Mb/s).
= 1: The speed of TSCK/MTSCK is double the data rate on the system side (4.096 Mb/s / 16.384 Mb/s).
= 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 the first bit of each Basic frame. In Transmit Multiplexed mode, MTSFS pulses dur-
= 1: In Transmit Non-multiplexed mode, if the CRC Multi-frame is to be generated, TSFSn pulses during the first bit of each CRC Multi-frame; if
