SAMPLE POWER COMMAND SEQUENCES
The following tables are examples of command sequence for power-up, power-down and display ON/OFF
operations. These are only to demonstrate some “typical, generic” scenarios. Designers are encouraged to
study related sections of the datasheet and find out what the best parameters and control sequences 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
Customer: These items are not necessary if customer parameters are the same as default
Advanced: We recommend new users to skip these commands and use default values.
Optional:
These commands depend on what users want to do.
