System Memory Map
7.4 Memory map
7.5 Interrupt controller
The MPT612 memory map incorporates several distinct regions, as shown in
addition, the CPU interrupt vectors can be re-mapped to allow them to reside in either
flash memory (the default) or on-chip static RAM.
The VIC accepts all of the interrupt request inputs and categorizes them as FIQ, vectored
IRQ and non-vectored IRQ as defined by programmable settings. The programmable
assignment scheme means that priorities of interrupts from the various peripherals can
be dynamically assigned and adjusted.
FIQ has the highest priority. If more than one request is assigned to FIQ, the VIC
combines the requests to produce the FIQ signal to the ARM processor. The fastest
possible FIQ latency is achieved when only one request is classified as FIQ because the
FIQ service routine does not need to branch into the interrupt service routine but can run
