In-System Programming for different devices
Specific of programming PICmicro
NOTE! Always carefully check connecting your ChipProg programmer to the target. Wrong
connecting may and probably will cause destruction of the programmer's and/or the target
system's hardware.
Most embedded microcontrollers have different algorithms for the ISP procedure. See the following
topics regarding the ISP for popular microcontrollers:

HV ISP Programming Mode (High-Voltage in-System Programming Mode). In this mode a relatively
high voltage of 13V is applied to the MCLR device pin. The user's equipment to be programmed
should be designed in the way tolerating a 13V signal to be applied to the MCLR device pin - in
particular this pin should not be connected to the Vcc pin of the device.
range varies from 2 to 5V for some PICmicro derivatives) the device being under programming must
have the 5V voltage level applied to the Vcc device pin. If in the working mode the target
microcontroller works under the Vcc lower than 5V and the target cannot tolerate applying the 5V
voltage to the Vcc pin, then, if the user needs to program the PICmicro device in-system, it is
necessary to change the schematic to have an ability to connect 5V to the Vcc pin while the target
is under the programming. However, verification of the correct programming can be conducted under
the voltages allowed by the manufacturer (Vcc min - Vcc max).
