(14) Read Identification (RDID)

The RDID instruction is for reading the manufacturer ID of 1-byte and followed by Device ID of 2-byte. The MXIC

Manufacturer ID and Device ID are listed as table of "ID Definitions".

The sequence is shown as Figure 25.

While Program/Erase operation is in progress, it will not decode the RDID instruction, so there's no effect on the cy-

cle of program/erase operation which is currently in progress. When CS# goes high, the device is at standby stage.

(15) 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 and the Device ID are shifted out on the falling edge of

SCLK with most significant bit (MSB) first as shown in Figure 26. The Device ID values are listed in Table of ID Defi-

nitions. 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.
