32-BIT ARM926EJ-S BASED MCU
7.10 Flash Memory Interface Controller (FMI)
The Flash Memory Interface (FMI) supports Secure Digital (SD, SDIO & MMC), Memory Stick (Memory stick
PRO) and NAND-type flash. FMI is cooperated with DMAC to provide a fast data transfer between system
memory and cards. There is one single 2048-byte buffer embedded in DMAC for temporary data storage.
Due to DMAC only has single channel, that means only one interface can be active at the same time.
Feature:
 Interface with DMAC for register read/write and data transfer
 4 interfaces are provided: Secure Digital(2.0)/MMC(4.2), Memory Stick/Memory Stick PRO and
NAND-type flash
 Using single 2048-byte shared buffer for data exchange between system memory and cards
