Bits | Field | Type | Reset | Description |
---|---|---|---|---|
31 | valid | r/o | 0 |
Indicates that the num field of this register is valid. This field is set whenever the FIQ Vector Address (Base Address + 0x1C) is read. It is cleared whenever the FIQ Vector Address (Base Address + 0x1C) is written. 1 – num field is valid (active FIQ interrupt) 0 – num field is invalid (no active FIQ interrupts) |
30:20 | reserved | r/o | 0 | Always read as 0. Writes have no effect. |
19:16 | pri | r/o | 0 | This field indicates the priority of the ACTIVE FIQ interrupt. This field is only valid if the valid flag (bit 31) is set. Otherwise the value is unpredictable |
15:10 | reserved | r/o | 0 | Always read as 0. Writes have no effect. |
9:0 | num | r/o | 0 |
This field indicates the interrupt number of the active FIQ interrupt. This field is loaded with the value from the Prioritized FIQ (Base Address + 0x0C) whenever the FIQ Vector Address (Base Address + 0x1C) is read. This field is only valid if the valid flag (bit 8) is set. Otherwise the value is unpredictable 0 – Interrupt 0 1 – Interrupt 1 1023 – Interrupt 1023 Note: The highest value is determined by the num_groups parameter |
