Isolating resistors:
Purpose of the R2, R3 resistors is to isolate the programmed chip from rest of target system.
Recommended value of resistors R2, R3 is 2k or more. You can also use jumpers instead of the
resistors.
ISP characteristics:
1. Programmer's output capability:
2. The cable length should be less then one foot.

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.
