PP voltage is applied the application circuit needs to take into consideration that the typical VPP voltage is 12V This may be an issue in the following situations 3 2 1 If the VPP pin is used as a MCLR pin The application circuit typically is connected to a pull up resistor capacitor circuit as recommended in the device data sheet Care must be taken so that the VPP voltage slew rate is not slowed down and exceeds the rise time in the programming specification typically 1 us If a supervisory circuit or a push button is interfaced to the MCLR pin it is recommended that they be isolated from the VPP voltage by using a Schottky type diode or limiting resistor as shown in Figure 3 1 For more information about using supervisory circuits with ICSP see Application Note AN820 System Supervisors in ICSP Architectures 0500820 3 2 2 If the VPP is used as an 1 0 port The application circuit that connects to the I O pin may not be able to handle the 12V voltage It is recommended to use a Schottky type diode or limiting resistor as shown in Figure 3 1 to isolate the circuitry 3 3 ISOLATE ICSPCLK OR PGC AND ICSPDAT OR PGD PINS The ICSPCLK or PGC and ICSPDAT or PGD pins need to be isolated from the application circuit to prevent the programming signals from being affected by the application circuitry ICSPCLK or PGC is a unidirection synchronous serial programming clock line from the programmer to the target ICSPDAT or
