XDOV … Transmit Data Overflow
More than 32 bytes have been written to the XFIFO.
XFW … Transmit FIFO Write Enable
Data can be written to the XFIFO.
Note: XFW is valid if CEC = 0 only!
XRNR … Transmit RNR (significant in auto-mode only!)
Indicates the status of the HSCX.
0 … receiver ready
1 … receiver not ready
RRNR … Receive RNR (significant in auto-mode only!)
Indicates the status of the remote station.
0 … receiver ready
1 … receiver not ready
RLI … Receive Line Inactive
Neither FLAGs as interframe time fill nor frames are received via the receive line.
Note: Significant in point-to-point configurations!
CEC … Command Executing
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.
Note: CEC will be active at most 2.5 transmit clock periods. If the HSCX is in power down
mode CEC will stay active.
CTS … Clear To Send State
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)
WFA … Waiting for Acknowledgement (significant in auto-mode only)
Indicates the ’Waiting for Acknowledgement’ status of HSCX.
