Control Register
All Control register bits are read and write accessible.
The Control register is recalled from parameter
EEPROM memory at power-up. Register bit values can
be modified in shadow RAM after power-up. Shadow
RAM values can be saved as the power-up default val-
ues by using the Copy Data command.
