Transmit FIFO - HDLC Channel 1 (Write)
XFIFO
XFIFO
Writing data to XFIFO of HDLC channel 1 can be done in 8-bit (byte) or 16-bit (word)
access. The LSB is transmitted first.
Up to 32 bytes/16 words of transmit data can be written to the XFIFO following an XPR
interrupt.

Receive Message Complete - HDLC Channel 1
Confirmation from CPU to FALC56 that the current frame or data
block has been fetched following an RPF or RME interrupt, thus the
occupied space in the RFIFO can be released. If RMC is given while
RFIFO is already cleared, the next incoming data block is cleared
instantly, although interrupts are generated.
Receiver Reset
The receive line interface except the clock and data recovery unit
(DPLL), the receive framer, the one-second timer and the receive
signaling controller are reset. However the contents of the control
registers is not deleted.
Transmission Repeat - HDLC Channel 1
If XREP is set together with XTF (write 24H to CMDR), the FALC56
repeatedly transmits the contents of the XFIFO (1 to 32 bytes) without
HDLC framing fully transparently, i.e. without flag, CRC.
The cyclic transmission is stopped with an SRES command or by
resetting XREP.
