B1RB
0 = Normal operation.
1 = L1TXD output set to a logic zero (used in GCI activation).
0 = One pulse wide prior to the 8-bit data.
1 = N pulses wide and envelopes the N-bit data.
00 = Normal operation.
01 = Automatic echo.
10 = Internal loopback.
11 = Loopback control.
0 = SDS2 signal is asserted during the B2 channel.
1 = SDS1 signal is asserted during the B2 channel.
0 = SDS1 signal is asserted during the B1 channel.
1 = SDS2 signal is asserted during the B1 channel.
00 = Channel not supported.
01 = Route channel to SCC1.
10 = Route channel to SCC2 (if MSC2 is cleared).
11 = Route channel to SCC3 (if MSC3 is cleared).
00 = Channel not supported.
01 = Route channel to SCC1.
10 = Route channel to SCC2 (if MSC2 is cleared).
11 = Route channel to SCC3 (if MSC3 is cleared).
