(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 6. 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 6. 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.

(16) Enter Secured Area (ENSA)
The ENSA instruction is for entering the additional 512-bit secured area mode. The additional 512-bit secured area
is independent from main array, which is used to store unique ID for system identifier. After entering the Secured
Area mode, follow standard read procedure to read out the data.
The sequence of issuing ENSA instruction is: CS# goes low→ sending ENSA instruction to enter Secured Area
mode→ CS# goes high.
Please note that WRSR/WRSCUR commands are not acceptable during the access of secure area region.
(17) Exit Secured Area (EXSA)
The EXSA instruction is for exiting the additional 512-bit secured area mode.
The sequence of issuing EXSA instruction is: CS# goes low→ sending EXSA instruction to exit Secured Area
mode→ CS# goes high.
