When interrupt nesting is enabled (or NSTDIS bit
(INTCON1<15>) is ‘0’), the following sequence of
events will lead to an address error trap:
1. REPEAT loop is active.
2. An interrupt is generated during the execution
3. The CPU executes the Interrupt Service
4. Within the ISR, when the CPU is executing the
of the REPEAT loop.
Routine (ISR) of the source causing the
interrupt.
first instruction cycle of the 3-cycle RETFIE
(Return from Interrupt) instruction, a second
interrupt is generated by a source with a higher
interrupt priority.

Work around
Processing of Interrupt Service Routines should
be disabled while the RETFIE instruction is being
executed. This may be accomplished in two
different ways:
1. Place a DISI instruction immediately before
2. Immediately prior to executing the RETFIE

interrupted by other higher priority interrupt
sources (with priority levels 1 through 6). This
is shown in Example 8 in the Timer1 ISR. In
this example, a DISI instruction inhibits level 1

cycles, while the RETFIE instruction is
executed.
instruction, increase the CPU priority level by
modifying the IPL<2:0> bits (SR<7:5>) to ‘111’
as shown in Example 9. This will disable all
interrupts between priority levels 1 through 7.
