around depends on the compiler in use. Please
refer to your C compiler documentation for
details.
If using the Microchip MPLAB
define both high and low priority interrupt han-
dler functions as “low priority” by using the
pragma interruptlow
directive instructs the compiler to not use the
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
spite of the pragma interruptlow directive.

The code segment shown in Example 2
demonstrates the work around using the C18
compiler. An optimized C18 version is also pro-
vided in Example 3. This example illustrates
how it reduces the instruction cycle count from
10 cycles to 3.
