EXAMPLE 4:

LOOP1: MOV
LOOP0: MOV
Note:
When using two DO loops in a nested fashion,
terminating the inner-level DO loop by setting the
EDT bit (CORCON<11>) will produce unexpected
results. Specifically, the device may continue
executing code within the outer DO loop forever.
This erratum does not affect the operation of the
MPLAB C30 compiler.
Work around
The application should save the DCOUNT Special
Function Register (SFR) prior to entering the inner
DO loop and restore it upon exiting the inner DO
loop. This work around is shown in
Affected Silicon Revisions
