When the most significant bit, A14, of the address bus is set to ’0’, the microprocessor is performing an access to
one of the device’s internal registers. Address bits A13-A0 indicate which particular register is being accessed.

Backplane Output Enable Bit
When LOW, the channel may be high impedance, either at the device output, or set by an
external buffer dependent upon the BORS pin.
When HIGH, the channel is active.
Source Stream Address Bits
The binary value of these 5 bits represents the input stream number.
Ignored when BMM is set HIGH.
Source Channel Address Bits / Message Mode Data
The binary value of these 8 bits represents the input channel number when BMM is set
LOW.
Transmitted as data when BMM is set HIGH.
Note: When BMM is set HIGH, in both ST-BUS and GCI-Bus modes, the BCAB[7:0] bits
are output sequentially to the timeslot with BCAB[7] being output first.
