Read Manufacture ID/ Device ID (REMS) (90H)
The Read Manufacturer/Device ID command is an alternative to the Release from Power-Down / Device ID
command that provides both the JEDEC assigned Manufacturer ID and the specific Device ID.
The command is initiated by driving the CS# pin low and shifting the command code “90H” followed by a 24-bit
address (A23-A0) of 000000H. After which, the Manufacturer ID and the Device ID are shifted out on the falling edge of
SCLK with most significant bit (MSB) first as shown below. If the 24-bit address is initially set to 000001H, the Device ID will
be read first.
