15:12 Number of  
0000 (identical to 1111)  
Sets the number of dummy clock cycles subse-  
quent to all FAST READ commands.  
The default setting targets the maximum al-  
lowed frequency and guarantees backward com-  
patibility.

register.  
Address bytes 0 = Enable 4B address  
1 = Enable 3B address (Default)  
Defines the number of address bytes for a com-

1. Settings determine device memory configuration after power-on. The device ships from  
the factory with all bits erased to 1 (FFFFh). The register is read from or written to by  
READ NONVOLATILE CONFIGURATION REGISTER or WRITE NONVOLATILE CONFIGURA-  
TION REGISTER commands, respectively.
