Data Sheet
NRM
PPPM(1..0)
SLEN
BISNC
MCS
Normal Response Mode
This bit is valid in HDLC Automode operation only and determines the
function of the Automode LAP-Controller:
NRM = ’0’
NRM = ’1’
PPP Mode Select
This bit field enables and selects the HDLC PPP protocol modes:
PPPM = ’00’ No PPP protocol operation. The HDLC sub-mode is
PPPM = ’01’ Octet synchronous PPP protocol operation.
PPPM = ’10’ Asynchronous PPP protocol operation.
PPPM = ’11’ Bit synchronous PPP protocol operation.
SYNC Character Length
This bit selects the SYNC character length in BISYNC/MONOSYNC
operation mode:
SLEN = ’0’
SLEN = ’1’
Enable BISYNC Mode
This bit is selects BISYNC/MONOSYNC operation:
BISNC = ’0’
BISNC = ’1’
Modulo Count Select
This bit is valid in HDLC Automode operation only and determines the
control field format:
MCS = ’0’
MCS = ’1’
Full-duplex LAP-B / LAP-D operation.
Half-duplex normal response mode (NRM) operation.
determined by bit field ’MDS’.
Note: Bit ’BCR’ in register CCR0 must be set to ensure
6 bit (MONOSYNC), 12 bit (BISYNC).
8 bit (MONOSYNC), 16 bit (BISYNC).
MONOSYNC operation.
BISYNC operation.
Basic operation, one byte control field (modulo 8 counter
operation).
Extended operation, two bytes control field (modulo 128
counter operation).
proper asynchronous reception.
