Framer Transmit Frame Synchronization Pulse
FTFRS is asserted synchronously to the transmission of the first
bit of the first timeslot of each frame.
Reference Clock
• Reference clock for the internal clock recovery circuit
• Depending on p_rx_em in pcfN: Optional emergency clock if

no transition on FRCLK is detected within 23 CLOCK cycles.
The segmentation continues using the RFCLK divided by four,
and using the byte-pattern programmed to a_emg_bpslct in
acfg for the cell payload.

Structured CES: Depending on “p_tx_mfs” in
“pcfN”:
0 = Double frame mode: FTMFS is asserted every
2 frames (250 µs)
1 = CRC multiframe mode: FTMFS is asserted
every 16 frames (2 ms))
Unstructured CES: Inactive level
FTMFS is active low
FTMFS is active high
