Framer Transmit Frame Synchronization Pulse
FTFRS is asserted synchronously to the transmission of the F-bit
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.
