Description

PA4 /

CIN+ /

CIN1- /

INT1A /

PG1PWM

ST /

CMOS /

Analog

The functions of this pin can be:

(1) Bit 4 of port A. It can be configured as digital input or two-state output, with

pull-high resistor.

(2) Plus input source of comparator.

(3) Minus input source 1 of comparator.

(4) External interrupt line 1A. It can be used as an external interrupt line 1. Both rising

edge and falling edge are accepted to request interrupt service and configurable

by register setting

(5) Output of 11-bit PWM generator PWMG1.

When this pin is configured as analog input, please use bit 4 of register padier to

disable the digital input to prevent current leakage. The bit 4 of padier register can be

set to “0” to disable digital input; wake-up from power-down by toggling this pin is also

disabled.

PA3 /

CIN0- /

TM2PWM /

PG2PWM

ST /

CMOS /

Analog

The functions of this pin can be:

(1) Bit 3 of port A. It can be configured as digital input or two-state output, with

pull-high resistor.

(2) Minus input source 0 of comparator.

(3) PWM output from Timer2

(4) Output of 11-bit PWM generator PWMG2

When this pin is configured as analog input, please use bit 3 of register padier to

disable the digital input to prevent current leakage. The bit 3 of padier register can be

set to “0” to disable digital input; wake-up from power-down by toggling this pin is also

disabled.

PA0 /

CO /

PG0PWM /

INT0

ST /

CMOS

The functions of this pin can be:

(1) Bit 0 of port A. It can be configured as digital input or two-state output, with

pull-high resistor.

(2) Output of comparator.

(3) Output of 11-bit PWM generator PWMG0.

(4) External interrupt line 0. It can be used as an external interrupt line 0. Both rising

edge and falling edge are accepted to request interrupt service and configurable

by register setting

The bit 0 of padier register can be set to “0” to disable wake-up from power-down by

toggling this pin.

PB7 /

CIN5- /

PG1PWM

ST /

CMOS /

Analog

The functions of this pin can be:

(1) Bit 7 of port B. It can be configured as digital input or two-state output, with

pull-high resistor.

(2) Minus input source 5 of comparator.

(3) Output of 11-bit PWM generator PWMG1.

When this pin is configured as analog input, please use bit 7 of register pbdier to

disable the digital input to prevent current leakage. The bit 7 of pbdier register can

be set to “0” to disable digital input; wake-up from power-down by toggling this pin is

also disabled.
