This application note provides code examples for effectively handling reentrant interrupt handlers in the LPC2000 devices. The following organization is been adopted for this application note.
1. Interrupt handling overview
2. Nesting of Interrupts
3. Code examples
It is assumed for this application note, that the user is familiar with the ARM7TDMI-S architecture. Also, for code examples relating to simple interrupt handling using FIQ and IRQ, please refer to the AN10254_1 application note available online. All the code examples provided in this application note were built on the Keil MicroVision3 ARM compiler (an evaluation version of which is free for download at www.keil.com)
