Isolating resistors:
Purpose of the R1..R3 resistors is to isolate the programmed chip from rest of target system.
Recommended value of resistors R1.. 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.
1.1 Vcc - 80 mA;
1.2 Vpp - 50 mA;
1.3 logical pins - 5 mA.

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.
