Detailed Register Description
VFR... Valid Frame
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 ... 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
FC
/FE
), and two programmable TEI values (TEI1, TEI2) plus a fixed group TEI (TEIG
H
H
of value FF
), are available for address comparison.
H
The result of the address comparison is given by SA1-0 and TA, as follows:
