Pin hold

Enable--Disable

Even though the GPIO pad hold function works in both input and output modes, it must be output capable GPIOs. If pad hold enabled: in output mode: the output level of the pad will be force locked and cannot be changed. in input mode: the input value read will not change, regardless of the changes of the input signal.

The state of digital GPIO cannot be held during Deep-sleep, and it will resume the hold function when the chip wakes up from Deep-sleep. If the digital GPIO also needs to be held during Deep sleep, gpio_deep_sleep_hold_en should also be called.

Deep sleep pin hold

Enable--Disable

When the chip is in Deep-sleep mode, all digital gpio will hold the state before sleep, and when the chip is woken up, the status of digital gpio will not be held. Note that the pad hold feature only works when the chip is in Deep-sleep mode, when not in sleep mode, the digital gpio state can be changed even you have called this function.
