OPERATING FEATURES  
SPI Modes  
The EN25F05 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). Both SPI bus operation Modes 0  
(0,0) and 3 (1,1) are supported. The primary difference between Mode 0 and Mode 3, as shown in  
Figure 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. For Mode 3 the  
CLK signal is normally high. In either case data input on the DI pin is sampled on the rising edge of the  
CLK. Data output on the DO pin is clocked out on the falling edge of CLK.  
This Data Sheet may be revised by subsequent versions  
or modifications due to changes in technical specifications.
