INSTRUCTIONS
Instructions are used to Read, Write (Erase and Program), and
configure the F25L32QA. The instruction bus cycles are 8 bits
each for commands (Op Code), data, and addresses. Prior to
executing any Page Program, Write Status Register, Sector
Erase, Block Erase, or Chip Erase instructions, the Write Enable
(WREN) instruction must be executed first. The complete list of
the instructions is provided in Table 5. All instructions are
entered and must be driven high after the last bit of the instruction
has been shifted in (except for Read, Read ID, Read Status
Register, Read Electronic Signature instructions). Any low to high
transition on CE , before receiving the last bit of an instruction
bus cycle, will terminate the instruction in progress and return the
device to the standby mode.
synchronized off a high to low transition of CE . Inputs will be
accepted on the rising edge of SCK starting with the most
Instruction commands (Op Code), addresses, and data are all
input from the most significant bit (MSB) first.
significant bit. CE must be driven low before an instruction is
