This is about specification that write to VCOM DAC of PMIC.
Example write operation is below.
Start
Slave Address

And PMIC can return ACK?
Start
Slave Address

Register Address
ACK
Data
Stop 15 ？ 00 S
6ms※
※In this period, Clock is Low , Data is High.
②If the period is 6ms between start condition and slave address,
register address and data.
