The NAND flash memory controller (FLCTL) provides interfaces with an external NAND-type
flash memory.
27.1
(1)
• Interface that can be connected to NAND-type flash memory
• Read or write in sector* units (512 + 16 bytes)
• Read or write in byte units
Note: * In the data sheet of NAND-type flash memory, an access unit of some products is
(2)
The FLCTL has two selectable access modes.
• Command access mode:
• Sector access mode:
(3)
• A sector is comprised of 512-byte data and 16-byte control code.
(4)
• When a program error or erase error occurs, the error is reflected on the error source flags.
Performs an access by specifying a command to be issued from the FLCTL to flash memory,
address, and data size to be input or output.
Read or write in physical sector units by specifying a physical sector. By specifying the
number of sectors, the continuous physical sectors can be read from or written to.
Interrupts for each source can be specified.
