Description

PA0~PA5

PA6/TMR0

PA7/TMR1

I/O

Pull-high

Wake-up

NMOS/CMOS/PMOS

Bidirectional 8-bit input/output port. Each pin can be configured as

a wake-up input by a configuration option. Software instructions de-

termine if the pin is a CMOS output or NMOS, PMOS or Schmitt

Trigger input. Configuration options determine if the structures are

CMOS, NMOS or PMOS types. Configuration options determine if

the pins have pull-high resistors. TMR0 and TMR1 are pin-shared

with PA6 and PA7, respectively.

PB0/SDI/SDA

PB1/SDO

PB2/SCK/SCL

PB3/SCS

PB4/PCK

PB5/INT

PB6~PB7

I/O

Pull-high

Wake-up

Bidirectional 8-bit input/output port. Each nibble can be configured

as a wake-up input by a configuration option. Software instructions

determine if the pin is a CMOS output or Schmitt Trigger input. Con-

figuration options determine if the pins have pull-high resistors. The

power supply for I/O pins PB0~PB7 can be selected to be VDD or

V33O using a configuration option. Pins PB0~PB3 are pin-shared

with the Serial Interface pins. Pin PB4 is pin-shared with the periph-

eral clock output and PB5 is shared with the external interrupt pin.

PC0/COM0

PC1/COM1

PC2/COM2

PC3/COM3

PC4~PC7

I/O

Pull-high

Wake-up

Bidirectional 8-bit input/output port. Each nibble can be configured

as a wake-up input by a configuration option. Software instructions

determine if the pin is a CMOS output or Schmitt Trigger input. Con-

figuration options determine if the pins have pull-high resistors.

PC0~PC3 are pin-shared with COM0~COM3

PD0~PD7

I/O

Pull-high

Wake-up

Bi-directional 8-bit input/output port. Each nibble can be configured

as a wake-up input by a configuration option. Software instructions

determine if the pin is a CMOS output or Schmitt Trigger input. Con-

figuration options determine if the pins have pull-high resistors.

PE0~PE7

I/O

Pull-high

Wake-up

Bidirectional 8-bit input/output port. Each nibble can be configured

as a wake-up input by a configuration option. Software instructions

determine if the pin is a CMOS output or Schmitt Trigger input. Con-

figuration options determine if the pins have pull-high resistors.

PF0, PF1

I/O

Pull-high

Wake-up

Bidirectional 2-bit input/output port. Each pin can be configured as

a wake-up input by a configuration option. Software instructions de-

termine if the pin is a CMOS output or Schmitt Trigger input. Config-

uration options determine if the pins have pull-high resistors.

USBPDP/CLK

I/O

USBPDP line. USB function is controlled by software control regis-

ters.

USBPDN/DATA

I/O

USBPDN line. USB function is controlled by software control regis-

ters.

RES

Schmitt trigger reset input. Active low

GND

¾¾

Digital negative power supply, ground

VDD

¾¾

Digital positive power supply

V33O

3.3V regulator output

Note: As the Pin Description table applies to the largest package size not all pin may exist on smaller packages.
