I'm using the KW2x MCU and am curious about using PTA19 as GPIO.
I'm using PTA18 as a modem CLK_OUT (MCU CLK_IN). This signal is running at 4MHz. Then my MCU is put into PEE mode to run at 48MHz.
According to everything I've read in the reference manual, I should be allowed to use PTA19 as a GPIO. However it is toggling states as if it were internally tied to a clocking signal. Does anyone know what steps I need to take to use PTA19 as a GPIO?
Note: I do have it configure as an INPUT with MUX ALT1.
