GPO_n_EN: Output enable of GPIO_n. n=0, 1, 2, 3.
1: Output.
0: Input.
GPI_n: Input level on GPIO_n pin when GPIO_n is an input pin. N=0, 1, 2, 3.
Note:If 70h.PME_PIN set to ‘0’, GPI_0 can be indicated as input level on GPIO_0 pin.
If 70h.PME_PIN set to ‘1’, GPI_0 can be indicated as PME output signal value.
