example on how to set these jumpers.
3.1.3 Base board: Typical Jumper settings
This section contains three figures that shows some typical jumper settings for the FLEX
base boards. Settings the jumpers in the correct way is important, because it allows you
to control some important features of the board, which influences the power consumption
and voltage settings of the board components. Please note that for the FLEX Full, there
are two typical settings, depending if the user needs to program the dsPIC or the PIC18.
The available jumpers are listed in Table 3.3. Please refer to Section
• JP3: allow to enable the input power monitoring leds of 5V and 3.3V before the
• JP4: enables the dsPIC (R) DSC controlled system led;
• JP5: allow to connect the logic GND line to PE;
• JP6: allow to use an external power supply instead of the internal 3.3V for the
• JP7: allow to use an external power supply instead of the internal 0V for the dsPIC
• JP8: allows to toggle the voltage reference on the ICSP programming connector
• JP15 and JP16: allows to use an external clock oscillator for the dsPIC (R) DSC;
switching circuitry;
dsPIC (R) DSC A/D converters positive voltage;
(R) DSC A/D converters negative voltage;
to be supplied to the ICD2 device between 5V and 3.3V;
if disabled, the two pins are used as normal GPIO pins;
