IO_OUTP_CTRL 1-2
The outputs (Output mode, Polarity) are controlled via two advanced feature
registers.
The Polarity flag determines whether the output is active low (0) or active
high (1). The output mode can be viewed in the table below. The current
status of the output can be queried and set via the PinState flag.
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.
