Command decoder
The command decoder identifies command words that
arrive on the I

C-bus:
Pairs of bytes

– 2nd byte contains information.
Stream of information bytes after Co = 0; display or
instruction data depending on last D/C.
Themost-significant bitof acontrolbyteisthecontinuation
bit Co. If this bit is logic 1, it indicates that only one byte,
either command or RAM-data, will follow. If this bit is
logic 0, it indicates that a series of bytes, either command
or RAM-data, may follow. The DB6 bit of a control byte is
the RAM-data/command bit D/C. When this bit is logic 1, it
indicates that a RAM-data byte will be transferred next.
If the bit is logic 0, it indicates that a command byte will be
transferred next.
