Interrupt status GPIO register (ISGPIOR)
The ISGPIOR register monitors the status of the interruption from a particular GPIO
pin interrupt source to the host. Regardless of the IEGPIOR bits are enabled or not,
the ISGPIOR bits are still updated. The ISG[15:0] bits are the interrupt status bits
corresponding to the GPIO[15:0] pins.
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
