Nonvolatile Configuration Register  
Nonvolatile Configuration Register  
This register is read from and written to using the READ NONVOLATILE CONFIGURA-  
TION REGISTER and the WRITE NONVOLATILE CONFIGURATION REGISTER com-  
mands, respectively. A register download is executed during power-on or after reset,  
overwriting the internal configuration register settings that determine device behavior.
