Sync Character Detected
Only valid in Hunt Mode.
This bit is set to ’1’ if a SYN character is found in the received data
stream after the ’HUNT’ command has been issued in register CMDRH.
The receiver now is in the synchronous state.
Receive Status Change Interrupt
This bit is valid in HDLC Automode only.
It is set to ’1’, if a status change of the remote station receiver has been
detected by receiving a S-frame with receiver ready (RR) or receiver not
ready (RNR) indication. Because only a status change is indicated via
this interrupt, the current status can be evaluated by reading bit ’RRNR’
in status register STARH.
Parity Error Interrupt
This bit is only valid if parity checking/generation is enabled via bit
’PARE’ in register CCR3H.
It is set to ’1’, if a character with wrong parity has been received. If
enabled via bit CCR3H:RFDF, this error status is additionally stored in
the receive status byte generated for each receive character.
Receive Pool Full Interrupt
This bit is set to ’1’ if the RFIFO threshold level, set with bit field
’RFTH(1:0)’ in register CCR3H, is reached. Default threshold level is 32
data bytes in HDLC/PPP modes, 1 data byte in ASYNC/BISYNC modes.
