Pin Assignment

Note:

Each VDD (VSS) pins must be connected to the power (ground) of the system.

Description

PA0/BZ

PA1/BZ

PA2

PA3/PFD

PA4~PA7

I/O

Wake-up

Pull-high

Buzzer

PFD

Bidirectional 8-bit input/output port. Each bit can be configured as a wake-up

input by configuration option. Software instructions determine if the pin is a

CMOS output or Schmitt trigger input with or without pull-high resistor (deter-

mined by pull-high options: bit option). Pins PA0, PA1 and PA3 are

pin-shared with BZ, BZ and PFD, respectively.

PB0/AN0~

PB7/AN7

I/O

Pull-high

Bidirectional 8-bit input/output port. Software instructions determine if the pin

is a CMOS output or Schmitt trigger input with or without pull-high resistor

(determined by pull-high option: bit option) or A/D input. Once a PB line is se-

lected as an A/D input (by using software control), the I/O function and

pull-high resistor are disabled automatically.

PC0~PC7

I/O

Pull-high

Bidirectional 8-bit input/output port. Software instructions determine if the pin

is a CMOS output or Schmitt trigger input with or without pull-high resistor

(determined by pull-high option: bit option).

PD0/PWM0

PD1/PWM1

PD2/PWM2

PD3/PWM3

I/O

Pull-high

PWM

Bidirectional 4-bit input/output port. Software instructions determine if the pin

is a CMOS output or Schmitt trigger input with or without a pull-high resistor

(determined by pull-high option: bit option). PD0~PD3 are pin-shared with

PWM0~PWM3 (dependent on PWM options).
