9.1.1
Standard SPI Instructions
The W25Q16DW is accessed through an SPI compatible bus consisting of four signals: Serial Clock
(CLK), Chip Select (/CS), Serial Data Input (DI) and Serial Data Output (DO). Standard SPI instructions
use the DI input pin to serially write instructions, addresses or data to the device on the rising edge of
CLK. The DO output pin is used to read data or status from the device on the falling edge of CLK.
SPI bus operation Mode 0 (0,0) and 3 (1,1) are supported. The primary difference between Mode 0 and
Mode 3 concerns the normal state of the CLK signal when the SPI bus master is in standby and data is
not being transferred to the Serial Flash. For Mode 0, the CLK signal is normally low on the falling and
rising edges of /CS. For Mode 3, the CLK signal is normally high on the falling and rising edges of /CS.
9.1.2
Dual SPI Instructions
The W25Q16DW supports Dual SPI operation when using instructions such as “Fast Read Dual Output
(3Bh)” and “Fast Read Dual I/O (BBh)”. These instructions allow data to be transferred to or from the
device at two to three times the rate of ordinary Serial Flash devices. The Dual SPI Read instructions are
ideal for quickly downloading code to RAM upon power-up (code-shadowing) or for executing non-speed-
critical code directly from the SPI bus (XIP). When using Dual SPI instructions, the DI and DO pins
become bidirectional I/O pins: IO0 and IO1.
