ISP (In-System Programming)

Definition
In-system
reprogramming of device positioned inside the end system.
Using a simple interface, the ISP programmer communicates
serially with the device, reprogramming nonvolatile memories
on the chip. In-system programming eliminates the physical
removal of chips from the system. This will save time and
money, both during development in the lab, and when updating
the software or parameters in the field.
Target device is the device (microcontroller, PLD, etc...),
which is to be in-system programmed.
Target system is the physical Printed Circuit Board (PCB),
which contains the device to be in-system programmed.
ISP programmer is programmer, which has in-system
programming

General rules for in-system programming
We recommended respect following rules to avoid damage PC,
ISP programmer, and target device or target system:
• Ensure common earth point for target system, ISP
programmer and PC.
• For laptop or other PC that is not connected to common earth
point: make hard - wired connection from laptop to common
earth point (for example use LPT or COM port D –
connector).
• Any devices connected to target system must be connected
to common earth point too.
