The gpio line is pulled low right after the assertion of HIB_WAKE which is prior to my initialization of the pin. Additionally, I do not the see pin changing during a power reset, only hibernation wake up.
The pin in question is GPIO_12 so it is not one of the pins with the pinstapping configuration options on power up.
Forgot to mention that this is a Murata 1GC module.
This happens if the Wi-Fi module wakes from hibernation on a time interval too.
GPIO_16 does not exhibit this behavior. Seems to be a HW glitch?
Solution was to isolate the reset line with external circuitry, but requires board rework and is not the desired solution.
Is there any errata or documentation for issues like this?
We are not observing any glitch in the GIO when it comes out of hibernation.
