Silicon Errata Issues
1. Module: CPU
EXAMPLE 1:
© 2010 Microchip Technology Inc.
Note:
When an instruction that writes to a location in the
address range of Y data memory (addresses
between 0x0900 and 0x09FF) is immediately
followed by a MAC-type DSP instruction that reads
a location also resident in Y data memory, the two
operations will not be executed as specified. This
is demonstrated in

This document summarizes all silicon
errata issues from all revisions of silicon,
previous as well as current. Only the
issues indicated by the shaded column in
the following tables apply to the current
silicon revision (A4).

EXAMPLE 2:
Work arounds
Work around 1:
Insert a NOP between the two instructions as
shown in
Work around 2:
If Work around 1 is not feasible due to real-time
application constraints, the user may take
precautions to ensure that a write operation
performed on a location in Y data memory is not
immediately
instruction that performs a read operation of a
location in Y data memory.
