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.
0xF1000308 IO_INP_CTRL3 Same as
IO_INP_CTRL1 Only Guppy board level cameras
0xF100030C IO_INP_CTRL4 Same as
IO_INP_CTRL1 Only Guppy board level cameras
Note

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.
