When device is programmed, pin VPP is driven to
approximately 10V. SI, SO, SCK pins are used by device for
In-system programming, therefore target system mustn’t affect
these signals during In-system programming to avoid
programming error. As well, RESET pin should be isolated (or
not affected) during programming the device.
