NT_STA_GPIO

Interrupt status GPIO register

Address:

0D, 0E, 0F

Type:

Reset:

0x00

Description:

The interrupt status GPIO register monitors the status of the interruption from a

particular GPIO pin interrupt source to the host. The INT_STA_GPIO bits are

constantly updated regardless whether the INT_EN_GPIO_MASK bits are enabled or

not. The ISG[17:0] bits are the interrupt status bits correspond to the GPIO[17:0] pins.

[17:0 ISG[x]

Interrupt status GPIO (where x = 17 to 0)

ISG[x] will be set to ‘1’ if an interrupt is detected on the corresponding GPIO pin.

Reading the INT_STA_GPIO register clears all interrupt status GPIO bits to ‘0’ which had been

set to ‘1’ prior to the read event.
