27. NAND Flash Memory Controller (FLCTL)
27.4
27.4.1
Two operating modes are supported.
• Command access mode
• Sector access mode
27.4.2
Command access mode is a mode that accesses flash memory by specifying a command to be
issued to flash memory, address, data, read or write direction, and number of times for the
registers. In this mode, DMA transfer of input or output data can be performed by using
FLDTFIFO.
(1)
Figure 27.2 shows an example of reading operation for NAND-type flash memory. In this
example, the first command is set to H'00, address data length is set to 3 bytes, and the number of
read bytes is set to 6 bytes in the data counter.
