The FIU supports single, dual or quad communication interface. the FIU controller can operate in following modes: - User Mode Access(UMA): provides flash access by using an indirect address/data mechanism. - direct rd/wr mode: maps the flash memory into the core address space. - SPI-X mode: used for an expansion bus to an ASIC or CPLD. The NPCM750/730/715/710 supports up to three FIU devices: - FIU0 supports two chip select. - FIU3 supports four chip select. - FIUX supports two chip select. The NPCM FIU driver tested on NPCM750 evaluation board.
