Description
The Electron documentation states that:
"System.sleep(uint16_t wakeUpPin, uint16_t edgeTriggerMode, long seconds) can be used to put the entire device into a stop mode with wakeup on interrupt or wakeup after specified seconds. In this particular mode, the device shuts network subsystem and puts the microcontroller in a stop mode with configurable wakeup pin and edge triggered interrupt or wakeup after the specified seconds. When the specific interrupt arrives or upon reaching the configured timeout"
"When the specific interrupt arrives" is incorrect. The Electron will wake-up on the given pin but also on an edge from the WKP pin or, as far as I know, any other interrupt source. This should be made absolutely clear. Based on the information provided I have a design with something wired to the 'WKP' pin, just in case I decided it was good to be woken up, and assuming that if I decided otherwise I could simply specify some other pin in the above call to remove the feature. It seems that is actually not possible.
