7.1 Commands of PCA8576F

The commands available to the PCA8576F are defined in Table 5.

[1]

Not used.

All available commands carry a continuation bit C in their most significant bit position as

shown in Figure 3.

When this bit is set logic 1, it indicates that the next byte of the transfer to arrive will also

represent a command. If this bit is set logic 0, it indicates that the command byte is the

last in the transfer. Further bytes will be regarded as display data (see Table 6).
