These GPIO pins could be used to generate internal interrupt 69 - GPIO3 and GPIO4 ORed.

Refer to the QorIQ LX2160A Reference Manual, 5.2 Internal Interrupt Sources and

20.5.1.4 GPIO interrupt event register (GPIER)

20.5.1.5 GPIO interrupt mask register (GPIMR)

20.5.1.6 GPIO interrupt control register (GPICR)

Hi,we need these port to be gpio input not out put,for example,such as 1s interrupt input ,10ms interrupt input , 1ms interrupt input ,0.5ms interrupt input  and so on; can we used these ports?
