27.4.5 Status
Read
The FLCTL can read the status register of a NAND-type flash memory. The data in the status
register of a NAND-type flash memory is input through the I/O7 to I/O0 pins and stored in the bits
STAT[7:0] in FLBSYCNT. The bits STAT[7:0] in FLBSYCNT can be read by the CPU. If a
program error or erase error is detected when the status register value is stored in the bits
STAT[7:0] in FLBSYCNT, the STERB bit in FLINTDMACR is set to 1 and generates an
interrupt to the CPU if the STERINTE bit in FLINTDMACR is enabled.
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 27.4.
