(HAL entry #11)
int HAL_FIQStatus(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 FIQ 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_IRQStatus.
