Initialization Protocol :

1. Initialization using the Internal Reset Circuit

The display can be initialized using the internal reset circuit if the Internal Power Supply Reset timing below is met. Note: toff represents the time of power off condition for a momentary power supply dip or when cycling power off then on. If the internal power supply reset timing cannot be met, the display will not operate normally. In this case, the display can be initialized through software.
