2. C Language Programming: The exact work
#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 */
around depends on the compiler in use. Please
refer to your C compiler documentation for
details.
If using the Microchip MPLAB
piler, define both high and low priority interrupt
handler functions as “low priority” by using the
pragma interruptlow directive. This direc-
tive instructs the compiler to not use the
// Handle low priority interrupts.
// Handle high priority interrupts.
_asm goto MyHighISR _endasm
_asm goto MyLowISR _endasm

RETFIE FAST instruction. If the proper high
priority interrupt bit is set in the IPRx register,
then the interrupt is treated as high priority in

directive.
The code segment shown in Example 3
demonstrates the work around using the C18
