Legend: L = VIL, H = VIH, X = VIL or VIH, = Pulse input. See DC Characteristics for voltage levels.
*1: Default active edge of CLK is the rising edge.
*2: Autoselect code can be read both Asynchronous and Synchronous Read operation
*3: WE can be VIL if OE is VIL, OE at VIH initiates the write operations.
*4: For four program operations, enable to input the same program command.
*5: Protect “outermost” 2 × 8K words on low end of the boot block sectors.(SA0 and SA1)
