Data Sheet
3.1.1
Characteristics:
All frames with valid addresses are accepted and the bytes following the address are
transferred to the P via RFIFO.
3.1.2
Characteristics:
Every received frame is stored in RFIFO (first byte after opening flag to CRC field).
3.1.3
Characteristics:
A comparison is performed on the first byte after the opening flag with SAP1, SAP2 and
“group” SAPI (FE
3.1.4
Characteristics:
A comparison is performed only on the second byte after the opening flag, with TEI1,
TEI2 and group TEI (FF
3.1.5
Characteristics:
In extended transparent mode fully transparent data transmission/reception without
HDLC framing is performed i.e. without FLAG generation/recognition, CRC generation/
check, bitstuffing mechanism. This allows user specific protocol variations.
Also refer to chapter 3.5.

3.2.1
3.2.1.1
The 64-byte cyclic RFIFO buffer has variable FIFO block sizes (thresholds) of 4, 8, 16 or
32 bytes which can be selected by setting the corresponding RFBS bits in the EXMR
register. The variable block size allows an optimized HDLC processing concerning frame
length, I/O throughput and interrupt load.
Non-Auto Mode (MDS2-0 = ’01x’)
Transparent Mode 0 (MDS2-0 = ’110’).
Transparent Mode 1 (MDS2-0 = ’111’).
Transparent Mode 2 (MDS2-0 = ’101’).
Extended Transparent Mode (MDS2-0 = ’100’).
