- value
- PinValue
The enumeration value to write to the GPIO pin.
If the GPIO pin is configured as an output, the method drives the specified value onto the pin according to the current pin mode for the pin.
If the GPIO pin is configured as an input, the method updates the latched output value for the pin. The latched output value is driven onto the pin when the configuration for the pin changes to output.
