When CMM is one, the device is programmed to perform one of the special per-channel transmission modes. Bits
PCC0 and PCC1 from connection memory are used to select the per-channel tristate or message mode as shown
in Table 13 on page 36.

In normal functional mode, these bits MUST be set to zero.
Message Data Bits
8-bit data for the message mode. Not used in the per-channel tristate.
Per-Channel Control Bits
These two bits control the corresponding entry’s value on the STio stream.
Connection Memory Mode = 1
If this is high, the connection memory is in the per-channel control mode
which is per-channel tristate or per-channel message mode.
