Data Sheet
SYNCH(7:0) Synchronization Character (high)
SYNCL(7:0) Synchronization Character (low)
This register is only valid in BISYNC protocol mode.
The synchronization (SYN) character format depends on the setting of
bit ’BISNC’ and ’SLEN’ in register CCR2L:
• MONOSYNC Mode (CCR2L.BISNC = ’0’)
• BISYNC Mode (CCR2L.BISNC = ’1’)
In transmit direction the SYN character is sent continuously if no data
has to be transmitted and interframe timefill control is enabled by setting
bit ’ITF’ to ’1’ in register CCR2H.
In receive direction the receiver monitors the data stream for occurence
of the specified SYN pattern if operating in ’HUNT’ mode (bit ’HUNT’ in
register CMDRH).
The SYN character is defined by register ’SYNCL’:
a) SLEN = ’0’: the 6 bit SYN character is specified by bits (5..0)
b) SLEN = ’1’: the 8 bit SYN character is specified by bits (7..0).
The SYN character is defined by registers ’SYNCL’ and ’SYNCH’:
a) SLEN = ’0’: the 12 bit SYN character is specified by bits (5..0) of
each register, i.e. SYN(11..0) = SYNCH(5:0), SYNCL(5:0)
b) SLEN = ’1’: the 16 bit SYN character is specified by bits (7..0) of
each register, i.e. SYN(15..0) = SYNCH(7:0), SYNCL(7:0).
