Note:
Register bits not described may exist in hardware due to the use of PEB 2081,
SBCX, core. Writing those bits other than the default value will cause unexpected

Description
C/I codes as in C/I channel
The indication can be read via monitor channel CI (3:0).
Time-Out Disable
0:
Monitor timeout (minimum 5 ms)
1:
The time-out function of the monitor transmitter can be disabled
to ease manual software debugging.
D-channel mode:
Specific D channel associated functions including the pins DRDY and
CEB/SSYNC:
00: Transparent D-channel, pins DRDY and CEB/SSYNC tristated.
10: LT-T mode:
D-channel collision resolution according to CCITT
I.430. Pin DRDY conveys control information
synchronous to D-channel timeslots to control
PEB 2075, IDEC (0: stop; 1: go).
LT-S mode:
D-channel access control by establishing a logical
passive bus structure, where the received D-channel is
ANDed with the other channels selected over pin
CEB and the resulting value is sent back as Echo bit.
11: LT-T mode:
D-channel collision resolution according to CCITT
I.430. Pin DRDY conveys asynchronous control
information to control SACCO-B in the ELIC,
PEB 20550. This mode is only applicable for a single
channel LT-T application (0: go; 1: stop).
LT-S mode:
D-channel access control via the central D-channel
arbiter unit of the PEB 20550, ELIC. Dependent on
the command, each channel mirrors the received
D-channel into the Echo channel inverted
