1.1 CARD Interface
The card controller, complied with SD/MMC specification, explains commands from SD/MMC host and
transfers data between SD/MMC host and flash.
1.2 Flash Access Interface
The flash access interface communicates with CPU. It also manages two channels of flash, based on flash
commands. Moreover, it implements defect processing, ECC, and address mapping, etc.
1.3 Embedded CPU
Embedded CPU performs arithmetic and logical operations. In addition, it extracts instruction from ROM and
SRAM, decodes and executes them. It also manages control and status signals between flash access interface and
itself.
