1. Module: MAC Class Instructions with ±4
© 2008 Microchip Technology Inc.
Sequential MAC class instructions, which prefetch
data from Y data space using ±4 address
modification, will cause an address error trap. The
trap occurs only when all of the following
conditions are true:
1. Two sequential MAC class instructions (or a
2. Both instructions prefetch data from Y data
3. Neither of the instructions uses an accumulator
Work around
The problem described above can be avoided by
using any of the following methods:
1. Inserting any other instruction between the two
2. Adding an accumulator write back (a dummy
3. Do not use the + = 4 or - = 4 address
4. Do not prefetch data from Y data space.

DO loop) that prefetch from Y data space.

EXAMPLE 1:
L0:DAW.b
L1: ....
dsPIC30F3010/3011
The Decimal Adjust instruction, DAW.b, may
improperly clear the Carry bit, C (SR<0>), when
executed.
Work around
Check the Carry bit status prior to executing the
DAW.b instruction. If the Carry bit is set, set the
Carry bit again after executing the DAW.b
instruction. Example 1 shows how the application
should process the Carry bit during a BCD addition
operation.
