Source Stream Address.
The binary value of these 4 bits represents the input stream number.
Source Channel Address.
The binary value of these 7 bits represents the input channel number.
Connection Memory Mode = 0.
If this bit is set low, the connection memory is in normal switching mode. Bit 1
to 11 represent the source stream number and channel number.
Reserved.
Message Data Bits: 8-bit data for the message mode.
Per-Channel Control Bits: These two bits control outputs.
Connection Memory Mode = 1. If this bit is set high, the connection memory
is in the per-channel control mode which is per-channel tristate, per-channel
message mode or per-channel BER mode.
