XFW … Transmit FIFO Write Enable
Note:
XRNR … Transmit RNR (significant in auto-mode only!)
RRNR … Receive RNR (significant in auto-mode only!)
RLI … Receive Line Inactive
Note:
CEC … Command Executing
Note:
CTS … Clear To Send State

Semiconductor Group
More than 32 bytes have been written to the XFIFO.
Data can be written to the XFIFO.
Indicates the status of the HSCX.
0 … receiver ready
1 … receiver not ready
Indicates the status of the remote station.
0 … receiver ready
1 … receiver not ready
Neither FLAGs as interframe time fill nor frames are received via the receive line.
0 … no command is currently executed, the CMDR register can be written to.
1 … a command (written previously to CMDR) is currently executed, no further command
can be temporarily written via CMDR register.
If the CIE bit in CCR2 is set, this bit indicates the state of the CTS pin.
0 … CTS is inactive (high signal at CTS)
1 … CTS is active (low signal at CTS)
Indicates the ’Waiting for Acknowledgement’ status of HSCX.
XFW is valid if CEC = 0 only!
Significant in point-to-point configurations!
CEC will be active at most 2.5 transmit clock periods. If the HSCX is in power down
mode CEC will stay active.
