Description

PA0~PA5

PA6/TMR0

PA7/TMR1

I/O

Pull-low

Pull-high

Wake-up

CMOS/NMOS/PMOS

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

wake-up input by ROM code option. The input or output mode is con-

trolled by PAC (PA control register).

Pull-high resistor options: PA0~PA7

Pull-low resistor options: PA0~PA5

CMOS/NMOS/PMOS options: PA0~PA7

Wake up options: PA0~PA7

PA6 and PA7 are pin-shared with TMR0 and TMR1 input, respectively.

PA0~PA5 can be used as USB mouse X1, X2, Y1, Y2, Z1, Z2 input for

mouse hardware wake-up function

PA6, PA7 can be used as USB mouse button input for mouse hardware

wake-up function

PB0/AN0

PB1/AN1

PB2/AN2

PB3/AN3

PB4/AN4

PB5/AN5

PB6/VRL

PB7/VRH

I/O

Pull-high

Analog input

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

CMOS output or Schmitt trigger input with pull-high resistor (determined

by pull-high options).

The PB can be used as analog input of the analog to digital converter

(determined by options).

PB6, PB7 can be used as USB mouse button input for mouse Hardware

wake-up function

PD0~PD7

I/O

Pull-high

Bidirectional I/O lines. Software instructions determine the CMOS out-

put or Schmitt trigger input with pull-high resistor (determined by 1-bit

pull-high option).

PD4 can be used as USB mouse button input for mouse hardware

wake-up function
