Common Voltage Output Pin, 1.2V (typ, respect to AVSS)
Normally connected to AVSS pin with a 0.1
μ
F ceramic capacitor in parallel with a
2.2
μ
F electrolytic capacitor. VCOM pin goes to AVSS when PMVCM bit = ”0”.
Reference Voltage Output Pin, 2.1V (typ, respect to AVSS)
Reference Voltage Output Pin, 2.1V (typ, respect to AVSS)
Normally connected to AVSS pin with a 0.1
