(14) Read Electronic Manufacturer ID & Device ID (REMS)
The REMS instruction is an alternative to the Release from Power-down/Device ID instruction that provides both the
JEDEC assigned manufacturer ID and the specific device ID.
The REMS instruction is very similar to the Release from Power-down/Device ID instruction. The instruction is initi-
ated by driving the CS# pin low and shift the instruction code "90h" followed by two dummy bytes and one bytes
address (A7~A0). After which, the Manufacturer ID for MXIC (C2h) and the Device ID are shifted out on the falling
edge of SCLK with most significant bit (MSB) first as shown in figure 25. The Device ID values are listed in Table of
ID Definitions on page 16. 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.
