The Standalone TwinCAN device provides two interface channels for communication
with a host microcontroller: a multiplexed address/data bus and a synchronous serial
channel (SSC). The SSC may also be used to read out the initial TwinCAN register
configuration from a serial EEPROM without requiring a host microcontroller. A Sleep
Mode and a Power-Down Mode can be activated in order to minimize power
consumption. The device's clock can be controlled by CAN messages.
