XFW … Transmit FIFO Write Enable
Data can be written to the XFIFOB.
Note: XFW is valid if CEC = 0 only!
XREP … Transmission Repeat
Contains the read back value of the corresponding command bit CMDRB:XREP.
RFR … Receive FIFO read enable
A ’1’ indicates, that valid data is in the RFIFOB and read access is enabled. RFR is set
with the RME- or RPF-interrupt and reset when executing the RMC-command.
RLI … Receive Line Inactive

CEC … Command Executing
0 … no command is currently executed, the CMDRB register can be written to.
1 … a command (written previously to CMDRB) is currently executed, no further
command can be temporarily written via CMDRB register.
Note: CEC will be active at most 2.5 transmit clock periods. If the IPAC is in power down
