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 is shown in Figure 25. If the 24-bit address is

initially set to 000001H, the Device ID will be read first. In QPI mode the dummy cycles can be configured

by C0H command. When the dummy cycle is configured to 4, addr [0] input must be 0.
