1. Supports all READ REGISTER commands except READ LOCK REGISTER.  
Notes:  
2. A READ NONVOLATILE CONFIGURATION REGISTER operation will output data starting  
from the least significant byte.  
READ NONVOLATILE CONFIGURATION REGISTER Command  
To execute a READ NONVOLATILE CONFIGURATION REGISTER command, S# is driv-  
en LOW. For extended SPI protocol, the command code is input on DQ0, and output on  
DQ1. For dual SPI protocol, the command code is input on DQ[1:0], and output on  
DQ[1:0]. For quad SPI protocol, the command code is input on DQ[3:0], and is output  
on DQ[3:0]. The operation is terminated by driving S# HIGH at any time during data  
output.  
The nonvolatile configuration register can be read continuously. After all 16 bits of the  
register have been read, a 0 is output. All reserved fields output a value of 1.  
READ VOLATILE or ENHANCED VOLATILE CONFIGURATION REGISTER Command  
To execute a READ VOLATILE CONFIGURATION REGISTER command or a READ EN-  
HANCED VOLATILE CONFIGURATION REGISTER command, S# is driven LOW. For ex-  
tended SPI protocol, the command code is input on DQ0, and output on DQ1. For dual  
SPI protocol, the command code is input on DQ[1:0], and output on DQ[1:0]. For quad  
SPI protocol, the command code is input on DQ[3:0], and is output on DQ[3:0]. The op-  
eration is terminated by driving S# HIGH at any time during data output.  
When the register is read continuously, the same byte is output repeatedly.
