I know lots will say use the search button and google it, but the answers I've come across are too complex and not in simple simple enough words.

My question is:

How do you attach an Eeprom to a Pic and store parts of the program in it and then call that when running the program in the Pic

for example If I was to play with "Roman Black Sound" program/examples it needs way more space than is in the Pic, i.e. needs an eeprom, how would I connect the eeprom and address it while writing and reading

Hope I've explained my question enough for people to understand what I'm asking.
