Note 1:
When one of the operands of instructions shown in
Table 3 is fetched from program memory using
Program Space Visibility (PSV), the STATUS
Register, SR and/or the results may be corrupted.
Work arounds
Work around 1: For Assembly Language
Source Code
To work around the erratum in the MPLAB ASM30
assembler, the application may perform a PSV
access to move the source operand from program
memory to RAM or a W register prior to performing
the operations listed in Table 3. The work around
for Example 2 is demonstrated in Example 3.

Refer to the “dsPIC30F/33F Programmer’s Reference Manual”, (DS70157), for details on the dsPIC30F
Instruction set.
The errata only affects these instructions when a PSV access is performed to fetch one of the source
operands in the instruction. A PSV access is performed when the Effective Address of the source operand
is greater than 0x8000 and the PSV bit (CORCON<2>) is set to ‘1’. In the examples shown, the data
access from program memory is made via the W1 register.
SR<1:0> bits represent Sticky Zero and Carry Status bits respectively.
SR<15:10> bits represent Accumulator Overflow and Saturation Status bits.

Examples of Incorrect Operation
dsPIC30F6011/6012/6013/6014
EXAMPLE 3:
These instructions are identified in Table 3.
Example 2 demonstrates a scenario where this
occurs.
Also, always use Work around 2 if the C compiler
is used to generate code for dsPIC30F6011/6012/
6013/6014 devices.
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.
