Description

PA7 /

ST /

CMOS

The functions of this pin can be:

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

pull-high resistor.

(2) X1 is Crystal XIN when crystal oscillator is used.

If this pin is used for crystal oscillator, bit 7 of padier register must be programmed “0”

to avoid leakage current. This pin can be used to wake-up system during sleep mode;

however, wake-up function is also disabled if bit 7 of padier register is “0”.

PA6 /

ST /

CMOS

The functions of this pin can be:

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

pull-high resistor.

(2) X2 is Crystal XOUT when crystal oscillator is used.

If this pin is used for crystal oscillator, bit 6 of padier register must be programmed “0”

to avoid leakage current. This pin can be used to wake-up system during sleep mode;

however, wake-up function is also disabled if bit 6 of padier register is “0”.

PA5 /

PRSTB /

PG2PWM

IO (OD)

ST /

CMOS

The functions of this pin can be:

(1) Bit 5 of port A. It can be configured as digital input or open-drain output, with

pull-high resistor.

(2) Hardware reset.

(3) Output of 11-bit PWM generator PWMG2.

This pin can be used to wake-up system during sleep mode; however, wake-up

function is also disabled if bit 5 of padier register is “0”. Pleas

e put 33Ω resistor in

series to have high noise immunity when this pin is in input mode.
