APPENDIX C: DIAGNOSTIC AND
CALIBRATION
REGISTERS
For dsPIC33FJ06GS101/102/202, dsPIC33FJ16GS402/
404/502/504, dsPIC33FJ32GS406/606/608/610 and
dsPIC33FJ64GS406/606/608/610 devices, the last six
instruction words of program memory store diagnostic
and calibration information. Any development tool that
modifies this memory must take care to preserve the data
contained in these registers.
Table C-1 provides an example of how the diagnostic
and calibration registers are read. This table can be
added to the programming executive between steps 1
and 2.
Table C-2 shows an example of how the diagnostic and
calibration registers are restored once the program
memory has been erased. This table can be added to
the programming executive between steps 4 and 5.
