22.4.4
Command access mode accesses flash memory by specifying a command to be issued to flash
memory, address, data, read/write direction, and number of times to the registers. In this mode, I/O
data can be transferred by the DMA via FLDTFIFO.
(1)
Figures 22.4 and 22.5 show examples of read operation for AND-type flash memory. In these
examples, the first command is specified as H'00 and address data length is specified as 2 bytes
(SA1 and SA2). (Only SA1 and SA2 are specified, while CA1 and CA2 are not specified.). In
addition, the number of read bytes is specified as 4 bytes in the data counter and H'FF is specified
as the second command.
