Note 1.
Note 2.
This is the required wait time from when the reference voltage is specified by the VLCD register (or when the internal voltage
boosting method is selected (LCDM0.MDSET1 and MDSET0 = 01b) if the default reference voltage value is used) until voltage
boosting starts (VLCON = 1).
This is the wait time from when voltage boosting is started (VLCON = 1) until display is enabled (LCDON = 1).
