Our intention is to wake up the nRFLEI from power-down using the external interrupts, perform some actions and return to power-down. There are three external control signals which need to do this.
I had someone do an evaluation in which they concluded that this would be possible, but I feel that is incorrect.
When I read the specification, in particular "Interrupt from pin GP INT0, GP INT1 or GP INT2 as selected by bits 3,4 or 5 in SFR INTEXP. Only one of the bits may be set at a time.", it sounds to me that only one of the pins can be set to cause the interrupt at a time.
Am I reading this correctly, or is this a status register which indicates where the interrupt occurred?
It's no problem to poll each of the three pins after receiving the interrupt and I imagine we can use some ultra low power OR gate to trigger the interrupt? Has anyone tackled a similar problem with this device? I imagine it's pretty common.
