27. NAND Flash Memory Controller (FLCTL)
(2)
The status read of NAND-type flash memory can be performed by inputting the command H'70 to
NAND-type flash memory. When the DOSR bit in FLCMDCR is set to 1 and writing is performed
in command access mode or sector access mode, the FLCTL automatically inputs H'70 to NAND-
type flash memory and status read is performed. During the status read of NAND-type flash
memory, the I/O7 to I/O0 pins indicate the following information as shown in table 27.5.
