INSTRUCTIONS
All instructions, addresses and data are shifted in
and out of the device, most significant bit 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, most significant bit
first, on Serial Data Input (D), each bit being
latched on the rising edges of Serial Clock (C).
The instruction set is listed in Table 4..
Every instruction sequence starts with a one-byte
instruction code. Depending on the instruction,
this might be followed by address bytes, or by data
bytes, or by both or none.
In the case of a Read Data Bytes (READ), Read
Data Bytes at Higher Speed (Fast_Read), Read
Status
Register
(RDSR),
Read
Identification
(RDID) or Release from Deep Power-down, and
Read Electronic Signature (RES) instruction, the
shifted-in instruction sequence is followed by a
data-out sequence. Chip Select (S) can be driven
High after any bit of the data-out sequence is be-
ing shifted out.
In the case of a Page Program (PP), Sector Erase
(SE), Bulk Erase (BE), Write Status Register
(WRSR), Write Enable (WREN), Write Disable
(WRDI) or Deep Power-down (DP) instruction,
Chip Select (S) must be driven High exactly at a
byte boundary, otherwise the instruction is reject-
ed, and is not executed. That is, Chip Select (S)
must 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 cy-
cle continues unaffected.
