cause substantial damage to the device. Functional operation of this device at other conditions beyond those listed
in the specification is not implied and prolonged exposure to extreme conditions may affect device reliability.
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.
