TCBR1/TCBR2/TCBR3/TCBR4: DEFINITION WHEN CCR3.6 = 1
*
Alarm bits.
The user can also take advantage of this functionality to intermix signaling data from the TSIG pin and
from the internal Transmit Signaling Registers (TS1 to TS16). As an example, assume that the user
wishes to source all the signaling data except for voice channels 5 and 10 from the TSIG pin. In this
application, the following bits and registers would be programmed as follows:
TSRE = 1 (CCR3.2)
TCBFS = 1 (CCR3.6)
T16S = 1 (TCR1.5)
CH1 and CH17 should be set to 1 to allow the internal TS1 register to create the CAS Multiframe Alignment Word and Spare/Remote
(MSB)

TS1 = 0Bh (MF alignment word, remote alarm etc.)
TCBR1 = 03h (source time slot 16, frame 1 data)
TCBR2 = 01h (source voice Channel 5 signaling data from TS6)
TCBR3 = 04h (source voice Channel 10 signaling data from TS11)
TCBR4 = 00h
