GPIO Module
Functional
Configuring global fastwake prevents a GPIO pin from sending data to the DIN register.
When configuring the fastwake-only bit of the CTL register and forcing data to a GPIO pin in run mode, the device will wake up, but the data on the GPIO pin will not appear in the DIN register. This is because the CTL register configuration prevents any data from flowing from the GPIO pin to the DIN register.
Avoid using the GPIO fastwake-only function when expecting data on a GPIO pin entering the DIN register.
