Instruction
All instructions, addresses, and data are shifted in and out of the device with the most
significant bit shifted first.
Serial Data Input (D) is sampled on the first rising edge of Serial Clock (C) after Chip Select
(S#) is driven Low. Then, the one-byte instruction code must be shifted in to the device with
the most significant bit entered first on Serial Data Input (D), and each bit being latched on the
rising edges of Serial Clock (C). The instruction set is listed in Table 7 below.
Depending on the instruction, the one-byte instruction code is followed by address bytes or
data bytes, or both, or none at all. Chip Select (S#) must be driven High after the last bit of
the instruction sequence has been shifted in.
At the end of a Page Program (PP), Block Erase (BE), Chip Erase (CE), or Write Status
Register (WRSR) instruction, Chip Select (S#) must be driven High exactly at a byte boundary.
Otherwise the instruction will be rejected and not executed. That is, Chip Select (S#) must be
driven High when the number of clock pulses after Chip Select (S#) being driven Low, is an
exact multiple of eight. All attempts to access the memory array during a Write Status
Register cycle, Program cycle, or Erase cycle are ignored, and the internal Write Status
Register cycle, Program cycle, or Erase cycle will continue ineffectively.
