Configuration of P1 and P1 when not used
How should the P1 and P1 be configured in the project if they are used only for ISSP?
Pin P1 & P1 can be used for ISSP programming / I2C Interface / GPIO. If these pins are not used except for ISSP programming, they may be left at their default state of StdCPU / HighZ Analog in the device editor.
