Doc ID 14489 Rev 5

GPIO_SET_PIN

GPIO set pin register

Address:

0x10

Type:

R/W

Reset:

0x00

Description:

GPIO set pin register.

Writing 1 to this bit causes the corresponding GPIO to go to 1 state.

Writing 0 has no effect.

GPIO_CLR_PIN

Clear pin state register

Address:

0x11

Type:

R/W

Reset:

0x00

Description:

GPIO clear pin state register.

Writing ‘1’ to this bit causes the corresponding GPIO to go to 0 state.

Writing ‘0’ has no effect.

GPIO_MP_STA

GPIO monitor pin state register

Address:

0x12

Type:

R/W

Reset:

0x00

Description:

GPIO monitor pin state.

Reading this bit yields the current state of the bit. Writing has no effect.

GPIO_DIR

GPIO set pin direction

Address:

0x13

Type:

R/W

Reset:

0x00

Description:

GPIO set pin direction register.

Writing ‘0’ sets the corresponding GPIO to input state, and ‘1’ sets it to output state.

All bits are ‘0’ on reset.
