LCD voltage boost control register 0 (VLCG0)
VLCG0 controls the voltage boost level during the voltage boost operation.
VLCG0 is set with an 8-bit memory manipulation instruction.
Reset signal generation sets VLCG0 to 00H.
Notes 1. Select the settings according to the specifications of the LCD panel that is used.
Cautions 1. Bits 1 to 5 must be set to 0.
