Reset Signaling Unit Counter
After setting this bit the SS7 signaling unit counter and error counter
are reset.The bit is cleared automatically after execution.
Note: The maximum time between writing to the CMDR2 register
Receive Message Complete - HDLC Channel 2
Confirmation from CPU to FALC
has been fetched following an RPF2 or RME2 interrupt, thus the
occupied space in the RFIFO2 can be released.
Transmission Repeat - HDLC Channel 2
If XREP2 is set together with XTF2 (write 24H to CMDR3), the FALC
repeatedly transmits the contents of the XFIFO2 (1 to 32 bytes)
without HDLC framing fully transparently, i.e. without flag, CRC.
The cyclic transmission is stopped with an SRES2 command or by
resetting XREP2.
Transmit HDLC Frame - HDLC Channel 2
After having written up to 32 bytes to the XFIFO2, this command
initiates the transmission of a HDLC frame.

and the execution of the command takes 2.5 periods of the
current system data rate. Therefore, if the CPU operates with
a very high clock rate in comparison with the FALC56's clock,
it is recommended that bit SIS.CEC should be checked before
writing to the CMDR2 register to avoid any loss of commands.
