EXAMPLE 2:
DS80496C-page 6
#pragma interruptlow MyLowISR
void MyLowISR(void)
{
}
// Although MyHighISR is a high priority interrupt, use interruptlow pragma so that
// the compiler will not use retfie FAST.
#pragma interruptlow MyHighISR
void MyHighISR(void)
{
}
#pragma code highVector=0x08
void HighVector (void)
{
}
#pragma code /* return to default code section */
#pragma code lowVector=0x18
void LowVector (void)
{
}
#pragma code /* return to default code section */
2. C Language Programming:
// Handle low priority interrupts.
// Handle high priority interrupts.
_asm goto MyHighISR _endasm
_asm goto MyLowISR _endasm
The exact work around depends on the
compiler in use. Consult the C compiler’s
documentation for details.
If using the Microchip MPLAB
Compiler, define both high and low-priority
interrupt handler functions as “low priority” by
using the pragma interruptlow directive.
This directive instructs the compiler to not use
INTERRUPT SERVICE ROUTINE IN C
®
C18 C
the RETFIE FAST instruction. If the proper
high-priority interrupt bit is set in the IPRx
register, the interrupt is treated as high priority
in spite of the pragma interruptlow
directive.
The code segment, shown in Example 2,
demonstrates the work around using the C18
compiler.
