8.32 READ PRODUCT IDENTIFICATION BY JEDEC ID OPERATION (RDJDID, 9Fh; RDJDIDQ, AFh)

The JEDEC ID READ instruction allows the user to read the manufacturer and product ID of devices. Refer to Table

8.8 Product Identification for Manufacturer ID and Device ID. After the JEDEC ID READ command (9Fh in SPI

mode, AFh in QPI mode) is input, the Manufacturer ID is shifted out MSB first followed by the 2-byte electronic ID

(ID15-ID0) that indicates Memory Type and Capacity, one bit at a time. Each bit is shifted out during the falling

edge of SCK. If CE# stays low after the last bit of the 2-byte electronic ID, the Manufacturer ID and 2-byte electronic

ID will loop until CE# is pulled high.
