IOT expension , add GPIO


on IOT expension card, by default 4 GPIO are suported

I need to have additional 2 GPIO (can also be only output or only input)

is it possible to define 2 of the IOT expension card as alternate finctions

besides the GPIO I only also need to keep the I2C pns functionality, all other are not used

You can take uart1 CTS as output and RTS pin as input

You can also check if the nReset pin is connecting to any gpio pin
