What needs to be noted when using GPIO interrupt wake-up? Issue Date：2015-04-01

The user must confirm I/O state based on the pre-determined trigger condition before entering Idle or Power-down mode.

For example, if the interrupt trigger condition is rising-edge or high level, the user must confirm if the I/O state before entering Idle or Power-down mode is low level. Conversely, if the interrupt trigger condition is falling-edge or low level, the user must confirm if the I/O state before entering Idle or Power-down mode is high level.
