9-23. Read Electronic Manufacturer ID & Device ID (REMS), (REMS2), (REMS4)
The REMS, REMS2, and REMS4 instruction provides both the JEDEC assigned Manufacturer ID and the spe-
cific Device ID.
The instruction is initiated by driving the CS# pin low and shift the instruction code "90h", "DFh" or "EFh" fol-
lowed by two dummy bytes and one byte address (A7~A0). After which, the Manufacturer ID for Macronix (C2h)
and the Device ID are shifted out on the falling edge of SCLK with most significant bit (MSB) first as shown in
the figure below. The Device ID values are listed in "Table 7. ID Definitions". If the one-byte address is initially
set to 01h, then the Device ID will be read first and then followed by the Manufacturer ID. 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. A0=0 will output the Manufacturer ID first and A0=1 will output Device ID first. A1~A23 are don't care.
2. Instruction is either 90(hex) or EF(hex) or DF(hex).
