Data Sheet
7.1.15
Value after reset: 0E
RSTA
VFR
Determines whether a valid frame has been received.
The frame is valid (1) or invalid (0).
A frame is invalid when there is not a multiple of 8 bits between flag and frame end (flag,
abort).
RDO
If RDO=1, at least one byte of the frame has been lost, because it could not be stored in
RFIFO.
CRC
The CRC is correct (1) or incorrect (0).
RAB
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
TA
SA1-0 are significant in non-auto-mode 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
FC/FE
of value FF
The result of the address comparison is given by SA1-0 and TA, as follows:
C/R
The C/R bit contains the C/R bit of the received frame (Bit1 in the SAPI address)
Note: The contents of RSTA corresponds to the last received HDLC frame; it is
duplicated into RFIFO for every frame (last byte of frame)

), and two programmable TEI values (TEI1, TEI2) plus a fixed group TEI (TEIG
