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.
- COVTE (INTCON1<8>) = 1
- SATA/SATB (CORCON <7/6>) = 0

__MathError:
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 (TSR) in
order to clear these Status bits and eventually clear
the MATHERR trap flag. This is shown in Example 7.
