1. Module: Malfunction of EMUC2 pin on
2. Module: MAC Class Instructions with ±4
© 2008 Microchip Technology Inc.
On the dsPIC30F2011/2012 devices, the EMUC2
pin is susceptible to negative voltage spikes and
requires additional protection.
Work around
The work around depends on the usage of the
EMUC2 pin.
• If the EMUC2 pin is not used, terminate pin to
• If the EMUC2 pin is used for emulation, connect
• If the EMUC2 pin is used for I/O, add low-pass
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 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

4. Do not prefetch data from Y data space.

EXAMPLE 1:
L0:DAW.b
L1: ....
dsPIC30F2011/2012
The Decimal Adjust instruction, DAW.b, may
improperly clear the Carry bit, C (SR<0>), when
executed.
Work arounds
Work around 1:
Check the state of the Carry bit 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.
Work around 2: For C Language Source Code
For applications using C language, MPLAB C30
versions 1.20.04 or higher provide the following
command-line switch that implements a work
around for the erratum.
Refer to the “readme.txt” file in the MPLAB C30
v1.20.04 toolsuite for further details.
