6.4 Memory map

The LPC2194 memory map incorporates several distinct regions, as shown in the

following figures.

In addition, the CPU interrupt vectors may be re-mapped to allow them to reside in

either Flash memory (the default) or on-chip static RAM. This is described in Section

6.20 “System control”.

6.5 Interrupt controller

The Vectored Interrupt Controller (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.
