GPIO

Available

Except the ANYKEY wake-up, the GPIO0 wake-up and the

GPIO15 wake-up, other GPIO functions are not executed in

this mode. After a wake-up, the settings before entering this

mode are resumed.

Except the GPIO0 wake-up

and the GPIO15 wake-up,

other GPIO functions are not

executed in this mode.

Before entering this mode,

the status is retained.

UART

Available

This IC does not enter this mode during communication. In

this mode, any UART functions are not executed. Only

when the API described in the “Programming Guide” is used

to control the UART, the settings before entering this mode

are resumed.

Deactivated.

Available

This IC does not enter this mode during communication. In

this mode, any SPI functions are not executed. After a

wake-up, the settings before entering this mode are

resumed.

Deactivated.

I2C

Available

This IC does not enter this mode during communication. In

this mode, any I2C functions are not executed. After a wake-

up, the settings before entering this mode are resumed.

Deactivated.

PWM

Available

Before entering this mode, this PWM function should be

stopped. After wake-up, the settings before entering this

mode are resumed.

Deactivated.

ADC

Available

This IC does not enter this mode during ADC is operated. In

this mode, ADC functions are not executed. After wake-up,

the settings before entering this mode are resumed.

Deactivated.
