11.2.33 Read Manufacturer / Device ID Quad I/O (94h)
The Read Manufacturer / Device ID Quad I/O instruction is an alternative to the Read Manufacturer /
Device ID instruction that provides both the JEDEC assigned manufacturer ID and the specific device ID
at 4x speed.
The Read Manufacturer / Device ID Quad I/O instruction is similar to the Fast Read Quad I/O instruction.
The instruction is initiated by driving the /CS pin low and shifting the instruction code “94h” followed by a
24-bit address (A23-A0) of 000000h, 8-bit Continuous Read Mode Bits and then four clock dummy
cycles, with the capability to input the Address bits four bits per clock. After which, the Manufacturer ID for
Winbond (EFh) and the Device ID are shifted out four bits per clock on the falling edge of CLK with most
significant bit (MSB) first as shown in figure 31. The Device ID values for the W25Q16CL is listed in
Manufacturer and Device Identification table. If the 24-bit address is initially set to 000001h the Device ID
will be read first and then followed by the Manufacturer ID. The Manufacturer and Device IDs can be read
continuously, alternating from one to the other. The instruction is completed by driving /CS high.

Note:
The “Continuous Read Mode” bits M(7-0) must be set to Fxh to be compatible with Fast Read Quad I/O instruction.
