GPIO raw interrupt status register

Offset: 0x414

Bits read HIGH 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 GPIO interrupt mask register (GPIO1_IE, ...). Bits read as LOW

indicate that corresponding input pins have not initiated an interrupt. This register is

read only, its bits are cleared by a reset.

GPIO raw interrupt

status register

00000000

Reflect the status of interrupts trigger conditions detection on

pins (raw, prior to masking).

GPIO masked interrupt status register

Offset: 0x418

Bits read HIGH reflect the status of input lines triggering an interrupt. Bits read as LOW

indicate that either no interrupt has been generated, or the interrupt is masked. This

bits are cleared by a reset. The contents of this register are made available externally

through the intra-chip (or on-chip) GPIO1_MIS, ... signals.

interrupt status

00000000

Masked value of interrupt due to corresponding pin.

0: PrimeCell GPIO line interrupt not active.

1: PrimeCell GPIO line asserting interrupt.
