(1) GIOB[2] cannot output a level on to terminal V10. Only the input functionality is supported so that the application can generate an
interrupt whenever the N2HET2_PIN_nDIS is asserted (driven low). Also, a pull up is enabled on the input. This is not programmable
using the GIO module control registers.
