10-23. Read Electronic Manufacturer ID & Device ID (REMS)

The REMS instruction returns both the JEDEC assigned manufacturer ID and the device ID. The Device ID val-

ues are listed in "Table 9. ID Definitions".

The REMS instruction is initiated by driving the CS# pin low and sending the instruction code "90h" followed by

two dummy bytes and one address byte (A7~A0). After which the manufacturer ID for Macronix (C2h) and the

device ID are shifted out on the falling edge of SCLK with the most significant bit (MSB) first. If the address byte

is 00h, the manufacturer ID will be output first, followed by the device ID. If the address byte is 01h, then the de-

vice ID will be output first, followed by the manufacturer ID. While CS# is low, the manufacturer and device IDs

can be read continuously, alternating from one to the other. The instruction is completed by driving CS# high.

Notes: (1) ADD=00H will output the manufacturer's ID first and ADD=01H will output device ID first.
