The EXCH instruction does not execute correctly.
Work around
If
recommended fix is to replace:
with:
If using the MPLAB C Compiler for dsPIC
(formerly known as the MPLAB C30 C Compiler),
specify the compiler option, -merrata=exch
(Project>Build Options>Projects>MPLAB
C30>Use Alternate Settings)

5. Module: CPU
The DISI instruction will not disable interrupts
when a DISI instruction is executed in the same
instruction
decrements to zero. For example, when user code
executes a DISI #7, interrupts for 7 + 1 cycles
(7 + the DISI instruction itself) are disabled. In
that case, the DISI instruction uses a counter that
counts down from 7 to 0. The counter is loaded
with 7 at the end of the DISI instruction.
If the user code executes another DISI on the
instruction cycle where the DISI counter has
become zero, the new DISI count is loaded; but,
the DISI state machine does not properly re-
engage and continue to disable interrupts. At this
point, all interrupts are enabled. The next time the
user code executes a DISI instruction, the feature
will act normally and block interrupts.
In summary, it is only when a DISI execution is
coincident with the current DISI count = 0, that the
issue occurs. Executing a DISI instruction before
the DISI counter reaches zero will not produce
this error – the DISI counter is loaded with the
new value, and interrupts remain disabled until the
counter becomes zero.
Work around
When multiple DISI instructions are executed in
the source code, make sure that subsequent DISI
instructions have at least one instruction cycle
between the time that the DISI counter
decrements to zero and the next DISI instruction.
Alternatively, make sure that subsequent DISI
instructions are called before the DISI counter
decrements to zero.
