The GPIO interrupt status register LSB monitors the status of the interruption from a
particular GPIO pin interrupt source to the host. Regardless whether the IEGPIOR
bits are enabled or not, the INT_STA_GPIO_LSB bits are still updated. The ISG[7:0]
bits are the interrupt status bits correspond to the GPIO[7:0] pins.
Interrupt status GPIO (where x = 7 to 0)
Read:
Interrupt status of the GPIO[x]. Reading the register will clear any bits that has been set to '1'
Write:
Writing to this register has no effects

The GPIO interrupt status register MSB monitors the status of the interruption from a
particular GPIO pin interrupt source to the host. Regardless whether the
GPIO_INT_EN bits are enabled or not, the GPIO_INT_STA bits are still updated. The
ISG[11:8] bits are the interrupt status bits corresponding to the GPIO[11:8] pins.
Interrupt status GPIO (where x = 11 to 8)
Read:
Interrupt status of the GPIO[x]. Reading the register will clear any bits that has been set to '1'
Write:
Writing to this register has no effects.
