NOTES:
1. Read timing characteristics during program and erase operations are the same as during read-only operations. Refer to AC
2. The on-chip WSM completely automates program/erase operations; program/erase algorithms are now controlled internally
3. Refer to command definition table for valid A
4. Refer to command definition table for valid D
5. Program/erase durations are measured to valid SRD data (successful operation, SR.7 = 1)
6. For boot block program/erase, RP# should be held at V
