CHAPTER 23 2M/3M BIT FLASH MEMORY
Sector erase suspend
Read operations of the flash memory while sector erase is suspended will output "1" if an
address for the sector being erased has been specified, or will output the read value of bit7
(DATA: 7) for the specified data item will be output in other cases. Which sector is being erased,
and whether that sector is in sector suspend state, can be identified by referring to the toggle bit
flag (DQ6).
Note:
If the automatic algorithm starts, read accesses to the specified address are not effective. In data
read operations, the other bits can be output provided the end of data polling flag (DQ7) is set.
Thus, read data after the end of the automatic algorithm only after the read access that confirms
the end of data polling.
