The LGT8F328P is a processor very similar to the ATMega328P. It is not a clone so it requires its own core. To support the PinChangeInterrupt library for the LGT8FxP family, please add the LGT8FxP to the supported platforms. This is easily done by adding the processor as LGT8FX8P in PinChangeInterrupt,Settings.h and PinChangeInterrupt.Boards.h like an ATmega328P.
