no longer be used. Other Flash memory sectors may still be used. The Error flag bit (DQ5)
is reset after a Reset Flash instruction.
Erase Time-out flag (DQ3)
The Erase Time-out flag bit (DQ3) reflects the time-out period allowed between two
consecutive Sector Erase instructions. The Erase Time-out flag bit (DQ3) is reset to ’0’ after
a Sector Erase cycle for a time period of 100 µs + 20% unless an additional Sector Erase
instruction is decoded. After this time period, or when the additional Sector Erase instruction
is decoded, the Erase Time-out flag bit (DQ3) is set to '1.'
