For chips that require a high voltage VPP pulse during programming, some external
|
||||
switching circuitry will be needed to allow the Arduino to control the VPP voltage. There
|
||||
is a header connected to the unused D13 pin that can support this. See the
|
||||
[Intel 8755 version of the hardware](hardware/#intel-8755a-hardware-version) for an
|
||||
example of voltage switching by TommyPROM.
