CHAPTER 21 FLASH MEMORY
❍ At sector erase temporary stop
If data is continuously read from the sector in the erase temporary stop status when flash
memory is in erase temporary stop read mode, bit 2 performs toggle operation. If data is
continuously read from a sector not in the erase temporary stop status when flash memory is
in erase temporary stop write mode, Bit 2 outputs 1. Bit 6 differs from bit 2 in that it performs
the toggle operation only during the normal write operation, erase operation, or erase
temporary stop write operation.
Note:
Bits 2 and 6 are simultaneously used to detect the erase temporary stop read mode (bit 2
performs toggle operation but bit 6 does not). Bit 2 is also used to detect erased sectors. If
data is read from an erased sector when the flash memory is executing an erase operation,
bit 2 performs the toggle operation.
