1.4.3 Program Memory and Logical Control Part
MT6573 platform storage circuit is completed by MCP, usually 4Gbit/2Gbit DDR +
4Gbit/4Gbit NAND.
BB Chip has a special EMI interface used to access external Memory; currently we
used in most of our projects is the MCP, the future may be used Nand Flash (by NFI
interface access).MCP stores important communication protocol software and mobile
control program and MMI software. MCU run relative FLASH software to coordinate
mobile operation, include RF and I/O interface control and respond to user operation.
