* These functions control the gpio pins on the CYW43439 not the RP2040.
* The pin assignments for the Raspberry Pi Pico W are:
*
* GPIO 0 - output - controls the onboard LED
* GPIO 1 - output - controls the onboard voltage regulator mode.
* GPIO 2 - input - Reads as non-zero if power supplied by USB or VBUS pin.
