Hardware
The debugging and programming side of the starter kit is controlled by a PIC18F67J50
microcontroller running at 48 MHz. The PIC18F67J50’s built-in USB engine provides
the communications interface between the starter kit and the host PC. The
microcontroller manages debugging or programming of the target PIC18F46J50 by
controlling the target’s MCLR, PGC1/EMUC1 and PGD1/EMUD1 signals. Target
clocking is provided by the PIC18F67J50.
A Microchip 25LC010A serial EEPROM is used to store the starter kit’s serial number
and debug control information.
