COMPLETE MMR LISTING
In the following MMR tables, addresses are listed in hexadecimal code. Access types include R for read, W for write, and R/W for read
and write.

Description
Active IRQ source.
Current state of all IRQ sources (enabled and disabled).
Enabled IRQ sources.
MMR to disable IRQ sources.
Software interrupt configuration MMR.
Base address of all vectors. Points to the start of the 64-byte memory block,
which can contain up to 32 pointers to separate subroutine handlers.

R
0x00000000
This register contains the subroutine address for the currently active IRQ
source.

R/W
0x00000000
Contains the interrupt priority setting for interrupt Source 1 to Source 7.
An interrupt can have a priority setting of 0 to 7. For example:
Bits[7:4] contain the priority level for Interrupt 1.
Bits[11:8] contain the priority level for Interrupt 2.
Bits[31:28] contain the priority level for Interrupt 7.
0x0024
IRQP1

R/W
0x00000000
Contains the interrupt priority setting for Interrupt Source 8 to Interrupt
Source 15. For example:
Bits[7:4] contain the priority level for Interrupt 9.
Bits[11:8] contain the priority level for Interrupt 10.
Bits[31:28] contain the priority level for Interrupt 15.
0x0028

R/W
0x00000000
Contains the interrupt priority setting for Interrupt Source 16 to Interrupt
Source 19.

Indicates the priority level of an FIQ that has just caused an FIQ
exception.
