GPIO SENSE->DETECT Pulse Length requirement nRF51

[Jon (jono)]

Hi I cannot find the minimum pulse length to trigger wakeup using DETECT from GPIO hw pin configured as SENSE pin in the data sheet for nRF51822.

Ex: set PIN_CNF[0].SENSE = High, and configure DETECT interrupt and go to system OFF mode.

How long pulse is required on pin0 to wake system from OFF mode.

No not duplicate. That topic discuss reaction time for software.

My question is regarding minimal puls length for wakeup from system off mode using SENSE->DETECT combo. I'm fully aware that I cannot detect which of all SENSE enabled pins that generated the DETECT, but that's not a problem.

I just want the requirement on the SENSE-part, and I cannot find this in the datasheet.
