Camera interfaces

IO_OUTP_CTRL 1-3

The outputs are controlled via 3 advanced feature registers (see Table 24:

Advanced register: Output control on page 68).

The Polarity field determines whether the output is inverted (1) or not (0). The

Output mode can be viewed in the table below. The current status of the output

can be queried and set via the PinState.

It is possible to read back the status of an output pin regardless of the output

mode. This allows for example the host computer to determine if the camera is

busy by simply polling the BUSY output.
