:Unexpected Results!
:Correct Results!
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 6.
Work arounds
Work around 1:
Insert a NOP between the two instructions as
shown in Example 7.
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.

__MathError:
Catastrophic accumulator overflow traps are
enabled as follows:
A carry generated out of bit 39 in the accumulator
causes a catastrophic overflow of the accumulator
since the sign bit has been destroyed. If a math
error trap handler has been defined, the processor
will vector to the math error trap handler upon a
catastrophic overflow.
If the respective Accumulator Overflow status bit,
OA or OB (SR<15/14>), is not cleared within the
trap handler routine prior to exiting the trap handler
routine, the processor will immediately re-enter the
trap handler routine.
Work around
If a math error trap occurs due to a catastrophic
accumulator overflow, the overflow status flags,
OA and/or OB (SR<15:14>), should be cleared
within the trap handler routine. Subsequently, the
MATHERR (INTCON1<4>) flag bit should be
cleared within the trap handler prior to executing
the RETFIE instruction.
Since the OA and OB bits are read-only bits, it will be
necessary to execute a dummy accumulator-based
instruction within the trap service routine in order to
clear these status bits, and eventually clear the
MATHERR trap flag. This is shown in Example 8.
