PEB 2254
General Functions and Device Architecture T1
Transparent Mode 1 (MODE.MDS2-0=101)
Characteristics: address recognition, FLAG - and CRC generation/check, bit-stuffing
Only the high byte of a 2-byte address field will be compared with registers RAH1/2. The
whole frame excluding the first address byte will be stored in RFIFO.
Transparent Mode 0 (MODE.MDS2-0=100)
Characteristics: FLAG - and CRC generation/check, bit-stuffing
No address recognition is performed and each frame will be stored in the RFIFO.
5.2.2
Extended Transparent Mode
Characteristics: fully transparent
In no HDLC mode, fully transparent data transmission/reception without HDLC framing
is performed, i.e. without FLAG generation/recognition, CRC generation/check, or
bit-stuffing. This feature can be profitably used e.g for:
• Specific protocol variations
• Transmission of a BOM frame
• Test purposes
Data transmission is always performed out of the XFIFO. In transparent mode, the
receive data are shifted into the RFIFO.
