The Power converter can supply either 3.3 V or 5 V. The array of jumpers J0–J9 selects 3.3 V or 5 V
voltage on the P3 connector, which connects to the Emulation Adapter.

For example, when J2 is in the 3V3 position, it supplies 3.3 V to pin 6 of the P3 connector. When J2
is in the 5V position, it supplies 5 V to pin 6 of the P3 connector pin.
Be careful not to supply 5 V to the microcontroller power supply pin, which has declared a
maximum voltage 3.3 V! Refer to the microcontroller documentation for detailed information
on power supply.

Clock source
If the target's crystal circuit microcontroller oscillator (if available) is not an adequate clock source,
insert the appropriate crystal into the Q1 socket, replace the default 22pF C1 and C2 capacitors
when necessary, and DIP switch DIP2 to position away from the white dot.
