The GPIORIS register is the raw interrupt status register. Bits read HIGH in GPIORIS reflect the status of interrupts trigger conditions detected (raw, prior to masking), indicating that all the requirements have been met, before they are finally allowed to trigger by GPIOIE. Bits read as zero indicate that corresponding input pins have not initiated an interrupt. This register is read only, and bits are cleared by a reset.
Table 3.8 shows the bit assignment of the GPIORIS register.
