When one of the operands of instructions shown in
Table 3 is fetched from program memory using
PSV, the STATUS Register, SR and/or the results
may be
identified in Table 3. Example 2 demonstrates one
scenario where this occurs.
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.

Instruction set.
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.

Also, always use Work around 2 if the C compiler
is used to generate code for dsPIC30F6010
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.
