Our customer would like to confirm the voltage of the LCD glass when disable and enable charge pump.
Because their products is battery operated application.
Here is my understanding.
When disable charge pump(CPSEL=0), the voltage of the LCD glass is depends on VDD.
When enable chaege pump(CPSEL=1), the voltage of the LCD glass is depends on LCD_GCR[RVTRIM] value. In other word, they can adjust the voltage of the LCD glass by LCD_GCR[RVTRIM], it voltage is VIREG(0.91V to 1.09V) * 3.
Am I correct?
Please advise as soon as possible.
