setting bit field CCR2L:MDS(1:0) to ’10’ and bit CCR2L:ADM to ’0’.
Receiver inactive, receive line is ignored.
Receiver active.
Disable signaling system #7 (SS7) support.
Enable signaling system #7 (SS7) support.
The receiver expects a 16 or 32 bit CRC within a HDLC
frame. CRC processing depends on the setting of bit
’RCRC’.
Frames shorter than expected are marked ’invalid’ or are
discarded (refer to
The receiver does not expect any CRC within a HDLC
frame. The criteria for ’valid frame’ indication is updated
accordingly (refer to
Bit ’RCRC’ is ignored.
The received checksum is evaluated, but NOT forwarded
to the receive FIFO.
The received checksum (2 or 4 bytes) is evaluated and
forwarded to the receive FIFO as data.
