(2) NAND-Type Flash Memory (2048 + 64 Bytes) Access
Figure 25.7 shows an example of read operation for NAND-type flash memory (2048 + 64 bytes).
In this example, the first command is specified as H'00, the second command is specified as H'30,
and address data length is specified as 4 bytes. The number of read bytes is specified as 4 bytes in
the data counter.
