Section 22 AND/NAND Flash Memory Controller (FLCTL)
(2) Status Read of NAND-Type Flash Memory
The status register of NAND-type flash memory can be read by inputting command H'70 to
NAND-type flash memory. If programming is executed in command access mode or sector access
mode while the DOSR bit in FLCMDCR is set to 1, the FLCTL automatically inputs command
H'70 to NAND-type flash memory and reads the status register of NAND-type flash memory.
When the status register of NAND-type flash memory is read, the I/O7 to I/O0 pins indicate the
following information as described in table 22.4.
