Interface description
I2C bus and mode control pins are use to control operation. Default values of all the
operating modes are deterministic, some of these values are intrinsic to the IC and some
are determined by configurations pins. The configuration pins are read at power-up and
copied into registers, which may later be modified using the I2C bus, if one is present. This
allows varied operation in an environment where NOI2C bus is present, while allowing full
control and override of pin programmed modes when used with I2C.
