Note
*: The power group of this GPIO PF14 pin belongs to the VDDIO9 power domain of MA35D1
series, the default voltage of VDDIO9 (power input F_VDDIO) is VDD1V8 (DC 1.8V) on the NuMaker-
SOM-MA35D16A81 board. Please make sure the power group voltage of this GPIO PF14 pin is set
at the equal voltage 1.8V on both NuMaker-SOM-MA35D16A81 board and NuMaker-BASE-
MA35D1B1 board.
