The TiedToOutput field indicates that an output and the corresponding input
share the same physical connector pin. Pins with TiedToOutput set to 1 can
be used as an output or input.

The Polarity field determines whether the input is inverted (0) or not (1).
See Table 22: Input configuration register on page 80.
The InputMode field can be seen in the following table.
The PinState field is used to query the current status of the input.
Input modes
Trigger delay
The cameras feature various ways to delay image capture based on external
trigger.

Make sure that output and input are not enabled at the same
time. In order to use a pin as an input (e.g. for external trig-
ger), its output driver (e.g. IntEna) needs to be switched off.
