FIQACK R Addr.: 0x5000_0018 Default: 0xFFFF_FFFF
Description Fast interrupt vector register with FIQ acknowledge
Confirmation of fast interrupt request by reading the associated
interrupt vector
Bit No. Name Description
2 – 0 FIVEC Binary code of FIQ number
31 – 3 Vector ID Valid FIQ vector: always ‘1’.
Default vector: always ‘1’ (also bits 2 – 0).
IRCLVEC W Addr.: 0x5000_001C Default: ----
Description Interrupt request clear vector
Immediate deletion of an interrupt request in the interrupt request register
Bit No. Name Description
3 – 0 IRCLVEC Binary code of the input number of the request to be deleted
7 unused
MASKALL R/W Addr.: 0x5000_0020 Default: '1'
Description Mask all Interrupts
Global disable for all IRQ interrupt inputs
Bit No. Name Description
0 MASKALL '0' = Enable all non-masked IRQ interrupt inputs
(consideration given to set mask bits)
'1' = Global disable for all IRQ interrupt inputs
(independent of the interrupt mask)
IRQEND W Addr.: 0x5000_0024 Default: ----
Description End-of-interrupt (IRQ)
Communicates to the IRQ interrupt controller the completion of the interrupt service routine
associated with the current request
Bit No. Name Description
Not used
FIQEND W Addr.: 0x5000_0028 Default: ----
Description End-of-interrupt (FIQ)
Communicates to the FIQ interrupt controller the completion of the interrupt service routine
associated with the fast interrupt request
Bit No. Name Description
Not used
FIQPR0 R/W Addr.: 0x5000_002C Default: 0x0000_0007
… ….
FIQPR7 R/W Addr.: 0x5000_0048 Default: 0x0000_0007
Description FIQ priority registers
Priority of the fast interrupt request at input FIQ0 to FIQ7 of the FIQ interrupt controller
Bit No. Name Description
2 – 0 FIQPR0 to 7 Binary code of the priority
7 – 3 Not used
FIQISR R Addr.: 0x5000_004C Default: 0x0000_0000
Description FIQ in-service register
Indication of the fast interrupt requests confirmed by the CPU
Bit No. Name Description
7 – 0 FIQISR Inputs 0 to 7 of the FIQ interrupt controller
'0' = Fast interrupt request not confirmed
'1' = Fast interrupt request has been confirmed
