Rev. 1.0
MCP Memory
6.0 Common Flash Memory Interface
Common Flash Memory Interface is contrived to increase the compatibility of host system software. It provides the specific information of the device,
such as memory size and electrical features. Once this information has been obtained, the system software will know which command sets to use to
enable flash writes, block erases, and control the flash component.
When the system writes the CFI command(98H) to address 55H , the device enters the CFI mode. And then if the system writes the address shown in
Table 16, the system can read the CFI data. Query data are always presented on the lowest-order data outputs(DQ0-7) only. In word(x16) mode, the
upper data outputs(DQ8-15) is 00h. To terminate this operation, the system must write the reset command.
