8.2.2 Read JEDEC ID (9Fh)
The Read JEDEC ID instruction is compatible with the JEDEC standard for SPI compatible serial memories
that was adopted in 2003. The instruction is initiated by driving the /CS pin low and shifting the instruction
code “9Fh” followed by 8 dummy clocks. The JEDEC assigned Manufacturer ID byte for Winbond (EFh)
and two Device ID bytes are then shifted out on the falling edge of CLK with most significant bit (MSB) first
as shown in Figure 6. For memory type and capacity values refer to Manufacturer and Device Identification
table.
