RDO ... Receive Data Overflow
If RDO=1, at least one byte of the frame has been lost, because it could not be stored in
RFIFOD. As opposed to the ISTAD.RFO an RDO indicates that the beginning of a frame
has been received but not all bytes could be stored as the RFIFOD was temporarily full.
CRC ... CRC Check
The CRC is correct (1) or incorrect (0).
RAB ... Receive Message Aborted
The receive message was aborted by the remote station (1), i.e. a sequence of seven
1’s was detected before a closing flag.
SA1-0 ... SAPI Address Identification
TA ... TEI Address Identification
SA1-0 are significant in non-automode with a two-byte address field, as well as in
transparent mode 3. TA is significant in all modes except in transparent modes 0 and 1.
Two programmable SAPI values (SAP1, SAP2) plus a fixed group SAPI (SAPG of value

of value FF
The result of the address comparison is given by SA1-0 and TA, as follows:

C/R ... Command/Response
The C/R bit contains the C/R bit of the received frame (Bit1 in the SAPI address)
Note: The contents of RSTAD corresponds to the last received HDLC frame; it is
