2.4.6 Automation and Control Connector [J25]

The EVM supports an interface to allow for automated control of the system, including functions like on/off, reset, and boot mode settings.

Note: In the DIR/Level column, output is to the camera module, input is from the camera module. Bi-Dir signals can be configured as either input or output.
Note: The signal polarity is identified with a trailing 'z' in the Pin Name, which indicates the signal is active LOW. For example, POWERDOWNz is an active low signal, meaning '0' = EVM is Powered Down, '1' = EVM is NOT Powered Down.
