Note
1. At power-on, an internal power-on reset signal is generated which resets the I2C-bus data bits to a pre-defined state.
When the internal data bits are found to be in a POR state (due to an actual power-on reset but also when set via
the I2C-bus) bit POR signals logic 1. Using the POR bit to detect occurrence of a power-on reset requires bit PORR
to be set to logic 1 after power-up. Setting bit PORR forces the POR bit to logic 0 independent of other I2C-bus bit
settings.
