DEVICE OPERATION (CONTINUED)
JEDEC ID READ COMMAND (READ PRODUCT IDENTIFICATION BY JEDEC ID)
OPERATION
The JEDEC ID READ instruction allows the user to
read the manufacturer and product ID of devices. Refer

by the first Manufacturer ID (9Dh) and the Device ID
(46h, in the case of the IS25CQ032), each bit shifted
out during the falling edge of SCK. If CE# stays low
after the last bit of the Device ID is shifted out, the
