=0, Register Address to be written, Data Write, STOP
If no STOP is issued, the Data Write can be continuously performed. If
the register address falls within the range that allows address auto-
increment, then register address auto-increment internally after every
byte of data being written. For those register addresses that fall within a
non-incremental address range, the address will be kept static
throughout the entire write operation. Refer to
register summary table
and non-increment. An example of a non-increment address is Data
Port for initializing the PWM.
