7.17 Command decoder
The command decoder identifies command bytes that arrive on the I
The commands available to the PCF8576D are defined in
Table 7.

All available commands carry a continuation bit C in their most significant bit position as
shown in
arrive will also represent a command. If this bit is reset, it indicates that the command byte
is the last in the transfer. Further bytes will be regarded as display data (see
