GIOA[0]/USB2.VP/USB_FUNC.RXDPI 2 I/O Pull Down Programmable, General-purpose I/O.
20 µA All GPIO terminals are
GIOA[1]/USB2.VM/USB_FUNC.RXDMI 5
capable of generating
GIOA[2]/USB2.TXDAT/USB_FUNC.TXDO/N2HET2[0]/EQEP 9
interrupts to the CPU on

IS
GIOB[3]USB2.RCV/USB_FUNC.RXDI 1 Pull Down
(1) GIOB[2] cannot output a level on to pin 55. 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
GPIO module control registers.
