Carrier Detect Enable.
0 = Disable.
1 = Enable GPI02 as an active low carrier detect pin (must also set SE2[3:2]
[GPIO2] = 01
Caller ID Monitor.
00 = Caller ID monitor disabled (Normal caller ID operation).
01 = Caller ID monitor enabled. Si2400 must detect channel seizure signal followed by
marks in order to report caller ID data.
10 = Caller ID monitor enabled. Si2400 must detect a DTMF A or D followed by marks in
order to report caller ID data.
11 = Caller ID monitor enabled. Si2400 must only detect marks in order to report caller ID
data.
Read returns zero.
Ninth Bit Function.
Only valid if the ninth bit escape is set S15[0] (NBE).
0 = Ninth bit equivalent to ALERT.
1 = Ninth bit equivalent to HDLC EOFR.
Blind Dialing.
0 = Blind dialing disabled.
1 = Enables blind dialing after dial timeout register S02 (CW) expires.
Modem Loopback.
0 = Not swapped.
1 = Swaps frequency bands in modem algorithm to do a loopback in a test mode.
Miscellaneous Characters.
0 = Disables “.” and “/” character echoing.
1 = Enables “.” and “/” character echoing to indicate tone on and tone off for !7 operation.
