Why not? A PIC can program another PIC, and a 16F877 can read its own
memory. But:
- the source PIC contains both its own code and the image for the second
PIC, so the image can not be the full 8k
- you will have to do the programming-tricks: wiggle the /MCLR and the
PGC/PGD lines, and generate the HVP (or restrict yourself to LVP).
