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.
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.
