Powering the target device:
There are two alternative options for powering the
targets:
1. The target gets power from the programmer (Vdd).
This is possible only if the target does not consume too
much energy. A capacity of the target power circuitry
should not exceed 50 uF.
2. The target gets power from a built-in or external
power supply. In this case the power output from the
programmer should not be connected with the target.
The target system should be tolerant to applying
logical signals with the voltage levels exceeding the
voltages on the target.
NOTE! It is strictly prohibited to power the target from
both the programmer and built-in or external power
supply simultaneously.
Isolating resistors:
Purpose of the R1..R4 resistors is to isolate the
