There are three memory blocks in each of these PICmicro® MICROCONTROLLERs. The Program Memory and Data Memory have separate buses, so that concurrent access can occur, and is detailed in this section. The EEPROM data memory block is detailed in Section 4.0. Additional information on device memory may be found in the PICmicro™ Mid-Range Reference Manual, (DS33023) if Recovery MICROCONTROLLER.
