10.2 INSTRUCTIONS
The instruction set of the W25X32A consists of fifteen basic instructions that are fully controlled through
the SPI bus (see Instruction Set table). Instructions are initiated with the falling edge of Chip Select (/CS).
The first byte of data clocked into the DIO input provides the instruction code. Data on the DIO input is
sampled on the rising edge of clock with most significant bit (MSB) first.
Instructions vary in length from a single byte to several bytes and may be followed by address bytes, data
bytes, dummy bytes (don’t care), and in some cases, a combination. Instructions are completed with the
rising edge of edge /CS. Clock relative timing diagrams for each instruction are included in figures 4
through 19. All read instructions can be completed after any clocked bit. However, all instructions that
Write, Program or Erase must complete on a byte boundary (CS driven high after a full 8-bits have been
clocked) otherwise the instruction will be terminated. This feature further protects the device from
inadvertent writes. Additionally, while the memory is being programmed or erased, or when the Status
Register is being written, all instructions except for Read Status Register will be ignored until the program
or erase cycle has completed.
