Resources

Output from the inverting Oscillator amplifier.

AVCC is the supply voltage pin for Port F and the A/D Converter. It should be externally

connected to VCC, even if the ADC is not used. If the ADC is used, it should be con-

nected to VCC through a low-pass filter.

This is the analog reference pin for the A/D Converter.

An external capacitor (typical > 470 nF) must be connected to the LCDCAP pin as

shown in Figure 99. This capacitor acts as a reservoir for LCD power (VLCD). A large

capacitance reduces ripple on VLCD but increases the time until VLCD reaches its target

value.
