3 Interrupt Recommendations and Examples
RECOMMENDATIONS AND EXAMPLES FOR THE INTERRUPT USAGE
3.1 Interrupt Vector Definition
By using the
#pragma
to use our standard template project, which contains a file called vectors.c which performs all
interrupt settings. The user may use or copy and modify this file for own projects.
Please make sure to always define the complete interrupt vector table in just one C module
and do not split it.
/* THIS SAMPLE CODE IS PROVIDED AS IS AND IS SUBJECT TO ALTERATIONS. FUJITSU */
/* MICROELECTRONICS ACCEPTS NO RESPONSIBILITY OR LIABILITY FOR ANY ERRORS OR */
/* ELIGIBILITY FOR ANY PURPOSES.
/*
/*---------------------------------------------------------------------------*/
#pragma
intvect DefaultIRQHandler 15
#pragma
intvect My_IRQHandler_1
#pragma
intvect DefaultIRQHandler
#pragma
intvect My_IRQHandler_2
#pragma
intvect My_IRQHandler_3
#pragma
intvect DefaultIRQHandler
#pragma
intvect DefaultIRQHandler
#pragma
intvect My_IRQHandler_4
#pragma
intvect My_IRQHandler_5
#pragma
intvect My_IRQHandler_6
#pragma

. . .
Please note, that if the Interrupt service functions are located in a different C module, their
prototypes have to be defined also for the vector definition.
3.2 Setting an Interrupt Level
The following code snippet assigns the level 24 to reload timer 0 and 1.
