Output modes
PinState 0 switches off the output transistor and produces a low level over the
resistor connected from the output to ground. The following diagram
illustrates the dependencies of the various output signals.

Output state follows PinState bit Using this mode, the Polarity bit has to be set to 0 (not
inverted). This is necessary for an error free display of
the output status.
