The following tables are examples of command sequence for power-up, power-down and display ON/OFF
operations. These are only to demonstrate some “

study related sections of the datasheet and find out what the best parameters and control sequences are for
their specific design needs.
C/D
The type of the interface cycle. It can be either Command (0) or Data (1)
W/R
The direction of data flow of the cycle. It can be either Write (0) or Read (1).
Type
Required: These items are required
