1.2.5 AC Characteristics - Write Operations
NOTES:
1. The timing characteristics for reading the status register during block erase, full chip erase, program and OTP program
2. A write operation can be initiated and terminated with either CE# or WE#.
3. Sampled, not 100% tested.
4. Write pulse width (t
5. Write pulse width high (t
6. t
7. Refer to Table 4 for valid address and data for block erase, full chip erase, program, OTP program or lock bit
