Comment
Programming clock, generated by the In-
System programmer (master).
programmer (master) to target MCU
being programmed (slave).
(slave) to In-System programmer
(master).
The two systems must share the same
common ground.
To enable In-System programming, the
target MCU Reset must be kept active.
To simplify this, the In-System
programmer should control the target
MCU Reset
To allow simple programming of targets
operating at any voltage, the In-System
programmer can draw power from the
target. Alternatively, the target can have
power supplied through the In-System
programming connector for the duration
of the programming cycle
