Bug

Target
NRF52

mbed-os sha:
e62a1b923 (HEAD -> mbed-os-5.6, tag: mbed_lib_rev154, tag: mbed-os-5.6.3)

Expected behavior

DigitalOut led(LED1, 1); should have the pint be set to HIGH output.

Actual behavior

In the gpio_mode(), the pin is resetted (gpiote_pin_uninit) and the output value gets lost during initialization of DigitalOut as it is not saved anywhere in the config.

Steps to reproduce

Simply create a DigitalOut led(pin, 1) with an LED connected to the pin that requires HIGH to be off.

@thinkberg Just to confirm, this looks like it is NRF5x target problem in the HAL rather than generic. From the look at the code, gpiote_pin_uninit is in the HAL.
