WFA
XRNR
RRNR
Wait For Acknowledgement
This status bit is significant in Automode only. It indicates whether the
Automode state machine expects an acknowledging I- or S-Frame for a
previously sent I-Frame.
WFA=’0’
WFA=’1’
Transmit RNR Status
This status bit is significant in Automode only. It indicates the receiver
status of the local station (SCC).
XRNR=’0’
XRNR=’1’
Received RNR (Receiver Not Ready) Status
This status bit is significant in Automode only. It indicates the receiver
status of the remote station.
RRNR=’0’
RRNR=’1’
No acknowledge I/S-Frame is expected.
The Automode state machine is waiting for an
achnowledging S- or I-Frame.
The receiver is ready and will automatically answer poll-
frames with a S-Frame with ’receiver-ready’ indication.
The receiver is NOT ready and will automatically answer
poll-frames with a S-Frame with a ’receiver-not-ready’
indication.
The remote station receiver is ready.
The remote receiver is NOT ready.
(A ’receiver-not-ready’ indication was received from the
remote station)
