7.2
The instruction set of the W25Q32BV consists of thirty five basic instructions that are fully controlled
through the SPI bus (see Instruction Set table1-3). Instructions are initiated with the falling edge of Chip
Select (/CS). The first byte of data clocked into the DI input provides the instruction code. Data on the DI
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 37. 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 ignored. 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.
