Program Cycle Waveforms
Sector Erase Cycle Waveforms
Notes:
1. OE must be high only when WE and CE are both low.
2. For sector erase, the address depends on what sector is to be erased. (See note 3 under Command Definitions.)
3. The t
WPH
time between the 5th and 6th bus cycle should be a minimum of 150 ns.
