Using Interrupts on Trizeps4-6

This application-note describes how to to use interrupts on Trizeps IV(M). It is also applicable for Trizeps V and Trizeps VI.

It explains extended features of the Seco Windows Embedded CE Board-Support-Package, to map any interrupt-source of the xscale-processor, including single GPIO-pins to an interrupt-number and on how to implement an Interrupt-Service-Thread (IST) or Interrupt-Service-Routine (ISR) to run on an interrupt-event.

Notes

An ISR-DLL is not allowed to import functions. To avoid importing functions from coredll.dll in Visual Studio, set Configuration Properties→Linker→Advanced→No Entry Point Yes (/NOENTRY). Set Configuration Properties→C/C++→Code Generation→Buffer Security Check to No (/GS-).

Wakeup-Interrupts

If GPIO’s are listed in one line, only one of them may serve as wakeupsource; view PXA27x- Developer-Manual for details).
