33793 Distributed System Interface (DSI) Sensor Interface
The 33793 is a slave Distributed System Interface (DSI) device that is optimized as a sensor interface. The device contains circuits to power sensors such as accelerometers and to digitize the analog level from the sensor. The device is controlled by commands over the DSI bus and returns measured data over the bus.
