HAL_IRQStatus

(HAL entry #5)
int HAL_IRQStatus(int device)
Entry
device Device number to query interrupt status for
Exit
0 Device is not interrupting
non-zero Device is interrupting

Use

This call is used to query whether device is requesting an interrupt, regardless of whether the interrupt controller is configured to generate IRQ interrupts for the device.

For hardware where all device interrupts can be configured as either IRQ or FIQ, this call is functionally equivalent to HAL_FIQStatus.
