A specific write sequence for IPC2 (Interrupt
Priority Control 2) SFR is required to prevent
possible data corruption in the IEC2 (Interrupt
Enable Control 2) SFR. Interrupts must be
disabled during this IPC2 SFR write sequence.
Work around
An example of this write sequence is shown in
Example 8.
When coding in C, the write sequence shown
above can be implemented using inline assembly
instructions. The equivalent write sequence using
the C30 compiler is shown in Example 9.

__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 10.
- COVTE (INTCON1<8>) = 1
- SATA/SATB (CORCON <7/6>) = 0
