Product data sheet
6.4 Memory map
6.5 Interrupt controller
In case of LPC2158 only, an 8 kB SRAM block intended to be utilized mainly by the USB
can also be used as a general purpose RAM for data storage and code storage and
execution.
The LPC2157/2158 memory map incorporates several distinct regions, as shown in
Figure
In addition, the CPU interrupt vectors may be remapped to allow them to reside in either
flash memory (the default) or on-chip static RAM. This is described in
“System
The Vectored Interrupt Controller (VIC) accepts all of the interrupt request inputs and
categorizes them as Fast Interrupt Request (FIQ), vectored Interrupt Request (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.
