Description

PA0~PA7

I/O

Pull-high

Wake-up

I/O lines with pull-high resistors (bit option). I/O modes of each line are con-

trolled by related control register bit (PAC). Each line of PA can be optioned

as a wake-up input (bit option). I/O configurations: Schmitt trigger/CMOS

PB0/AN0~

PB7/AN7

I/O

Pull-High

I/O lines with pull-high resistors (bit option). I/O modes of each line are con-

trolled by related control register bit (PBC). I/O configurations: Schmitt trig-

ger/CMOS. Each PB line is pin shared with an A/D converter input.

PC0~PC6,

PC7

I/O

Pull-High

I/O lines with pull-high resistors (bit option). I/O modes of each line are con-

trolled by related control register bit (PCC). I/O configurations: Schmitt trig-

ger/CMOS.

PD0/PWM0~

PD3/PWM3,

PD4/INT0,

PD5/INT1,

PD6/TMR,

PD7

I/O

Pull-High PWM

Interrupt Falling

and/or Rising

I/O lines with pull-high resistors (bit option). I/O modes of each line are con-

trolled by related control register bit (PDC). I/O configurations: Schmitt trig-

ger/CMOS. The PD0~PD3 can be selected as PWM outputs. INT0/INT1

are falling/rising edge selectable triggers.
