All available commands carry a continuation bit C in their most significant bit position as
shown in Figure 18 . When this bit is set, it indicates that the next byte of the transfer to
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 Table 10 ).
