Jumper
2:
When programming the dsPIC device on the PICDEM MC LV Develop-
ment Board, the two DIP switches must be in the PRGM position. This
will ensure the programming pins are connected to the programmer. If the
user has generated independent code, the user must select
EMUC2/EMUD2 pins for emulation in the MPLAB Configuration menu.
These alternate pins will then be programmed and will be used for the
debugging or run phase.
After programming the dsPIC device, the user can disconnect the pro-
grammer from the ICD 2 plug J6 and run the device in Stand-Alone mode.
Alternatively, if the ICD 2 is being used in the Emulator mode, then the
DIP switches have to be switched to the DEBUG position. Then, the
EMUC2/EMUD2 pins will be connected to the ICD 2, and assuming the
configuration was done as described above, the user will be able to run
the firmware using the ICD 2 as an emulator.
