6. Module: Early Termination of Nested DO
EXAMPLE 4:
DS80195H-page 6
LOOP1: MOV
LOOP0:
Note:
When using two DO loops in a nested fashion,
terminating the inner-level DO loop by setting the
EDT(CORCON<11>) bit 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 SFR
prior to entering the inner DO loop and restore it
upon exiting the inner DO loop. This work around is
shown in Example 4.
.include “p30fxxxx.inc”
.......
DO #CNT1, LOOP0
....

For details on the functionality of
EDT bit, see section 2.9.2.4
in the dsPIC30F Family Reference
Manual.

7. Module: Y Data Space Dependency
EXAMPLE 5:
EXAMPLE 6:
When an instruction that writes to a location in the
address range of Y data memory (addresses
between 0x1800 and 0x27FF) is immediately
followed by a MAC-type DSP instruction that reads
a location also resident in Y data memory, the two
operations will not be executed as specified. This
is demonstrated in Example 5.
Work arounds
Work around 1:
Insert a NOP between the two instructions as
shown in Example 6.
Work around 2:
If work around #1 is not feasible due to application
real-time
precautions to ensure that a write operation
performed on a location in Y data memory is not
immediately
instruction that performs a read operation of a
location in Y data memory.
