Each pin on Port A can be programmed through a configuration option to have a wake-up function.
Individual pins can be selected to have a pull-high resistor.
Pins V2, C1, C2 and segment pin SEG34 are not available on the 52-pin QFP package.
Pins PB4/AN4~PB7/AN7 only exist on the 100-pin QFP package.
Pins PC0~PC5 only exist on the 100-pin QFP package.
Pin PD3/PWM3 only exists on the 100-pin QFP package.
Pins PD7/TMR1 and PC0/TMR2 only exist on the 100-pin QFP package. The 56-pin SSOP and 52-pin QFP
packages have only one external timer input TMR0.
Segment pins SEG0~SEG15 and SEG35~SEG45 only exist on the 100-pin QFP package.
For the 52-pin QFP and 56-pin SSOP, the VREF, AVDD are bonded together with VDD pin.
For the 52-pin QFP and 56-pin SSOP, the AVSS is bonded together with VSS pin.
