Notes: 1. I/O5 switches to a “1” when a program or an erase operation has exceeded the maximum time limits or when a program or
sector erase operation is performed on a protected sector.
2. I/O3 switches to a “1” when the VPP level is not high enough to successfully perform program and erase operations.
