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
RETFIE FAST instruction. If the proper high
priority interrupt bit is set in the IPRx register,
// Handle low priority interrupts.
// Handle high priority interrupts.
_asm goto MyHighISR _endasm
_asm goto MyLowISR _endasm
