I was referring to the dedicated EEPROM in PIC16/18, which is usually=20
very small - that link is talking of the program (flash) memory.
Also, the program memory is not volatile, it is flash memory - it needs=20
to store your program between power cycles so it has to be non-volatile.
PIC32 does not have "proper" EEPROM like the PIC16F EEPROM I referred=20
to, hence the EEPROM emulation library which uses the flash memory.
I would guess you have at least 128K of flash space available  - I have=20
used that part number before but I can't remember exactly how much it=20
has. I would have a good read of the PIC32 Family Reference Manual=20
(available in sections on the microchip website) as it will probably=20
clear a few things up for you, and go into detail about program memory.
