Preliminary data sheet
6.4 Memory map
6.5 Interrupt controller
In case of LPC2148 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 LPC2142/2148 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 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.
