Alvium CSI-2 Cameras User Guide V2.8.1
Non-isolated, programmable GPIOs
GPIOs description
The camera has four non-isolated GPIOs that can be configured by software to act
as inputs or outputs.
Alvium GPIOs use the push-pull technology to switch the signal level between low
and high. For low levels, the signal is "pulled" down towards ground level. For high
levels, the signal is "pushed" up towards VCC level.
I/O use for UART
Table 109
shows which values must be selected to control I/Os using
LineSelector.

Available GPIOs
From four GPIOs, I2C uses two GPIOs for control traffic. Therefore, only two GPIOs
are available for user control of the camera.
I/O cables maximum length
The maximum length for I/O cables must not exceed 30 m.
