Notes: 1. The subclock oscillator does not stop, but clock supply is halted.
13.3.4
When a large panel is driven, the on-chip power supply capacity may be insufficient. If the power
supply capacity is insufficient when V
must be reduced. This can be done by connecting bypass capacitors of around 0.1 to 0.3 µF to
pins V
