HD66765
Instruction Setting Flow
When the common driver HD66764 is used, follow the below about each instruction setting. The
instruction setting for the common driver is executed by the serial interface. When the instruction for the
common driver is set, the serial transfer must be executed to the common driver. The transfer to the
common driver must be executed immediately after the instruction set.
Follow the below serial transfer flow about each setting and then transfer must be executed.
