Can the CCG3PA (CYPD3171) be woken up from one of the sleep modes ( sleep mode or deep sleep mode) via a GPIO? If so, is there an app note that describes how to configure such functionality? I do not see any details in the datasheet.
An interrupt on any GPIO should be able to wake the device from sleep / deep sleep.
The ISR will be serviced in active mode and eventually if conditions are appropriate, it will fall back into deep sleep.
