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.
XFW is valid if CEC = 0 only!
Note:
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.
Significant in point-to-point configurations!
Note:
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.
CEC will be active at most 2.5 transmit clock periods. If the HSCX is in power down
mode CEC will stay active.
Note:
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.
