Description

PB6 /

TM3PWM /

CIN2- /

PG1PWM

ST /

CMOS /

Analog

This pin can be used as:

(1) Bit 6 of port B. It can be configured as digital input or two-state output with,

pull-up resistor by software independently.

(2) Minus input source 2 of comparator.

(3) Output of 8-bit timer Timer3 (TM3)

(4) Output of 11-bit PWM generator PWMG1

When this pin is configured as analog input, please use bit 6 of register pbdier to

disable the digital input to prevent current leakage. This pin can be used to

wake-up system during sleep mode; however, wake-up function is also disabled if

bit 6 of pbdier register is “0”.

PB5 /

TM3PWM /

PG0PWM

ST /

CMOS /

Analog

This pin can be used as:

(1) Bit 5 of port B. It can be configured as digital input or two-state output with,

pull-up resistor by software independently.

(2) Output of 8-bit timer Timer3 (TM3)

(3) Output of 11-bit PWM generator PWMG0

When this pin is configured as analog input, please use bit 5 of register pbdier to

disable the digital input to prevent current leakage. This pin can be used to

wake-up system during sleep mode; however, wake-up function is also disabled if

bit 5 of pbdier register is “0”.

PB4 /

TM2PWM /

PG0PWM

ST /

CMOS /

Analog

This pin can be used as:

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

pull-up resistor by software independently.

(2) Output of 8-bit timer Timer2 (TM2)

(3) Output of 11-bit PWM generator PWMG0

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

disable the digital input to prevent current leakage. This pin can be used to

wake-up system during sleep mode; however, wake-up function is also disabled if

bit 4 of pbdier register is “0”.

PB3 /

PG2PWM

ST /

CMOS /

This pin can be used as:

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

pull-up resistor by software independently.

(2) Output of 11-bit PWM generator PWMG2

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

disable the digital input to prevent current leakage. This pin can be used to

wake-up system during sleep mode; however, wake-up function is also disabled if

bit 3 of pbdier register is “0”.
