Command decoder
The command decoder identifies command bytes that
arrive on the I
2
C-bus. The most significant bit of a
command is the continuation bit C (see Fig.12). When this
bit is set, it indicates that the next byte to be transferred will
also be a command. If the bit is reset, it indicates the
conclusion of the command transfer. Further bytes will be
regarded as display data. Commands are transferred in
WRITE mode only.
The five commands available to the PCF8579 are defined
in Tables 2 and 3.
C = 0; last command.
C = 1; commands continue.
