Transmit FIFO (Write)
Writing data to XFIFO 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
(or ALLS) interrupt.

Receive Message Complete
Confirmation from CPU to FALC
block has been fetched following an RPF or RME interrupt, thus the
occupied space in the RFIFO can be released.
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. Receiver reset shall be done after every new
device initialization.
Transmission Repeat
If XREP is set together with XTF (write 24H to CMDR), the FALC
repeatedly transmits the contents of the XFIFO (1 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.
Note:During cyclic transmission the XREP-bit has to be set with every
RRES
H
write operation to CMDR.
