* @brief       Device driver for the NCV7356 Single Wire CAN Transceiver
*
* The NCV7356 is a physical layer device for a single wire data connection
* such as Bosch's Controller Area Network (CAN) protocol.
* The device is capable of transmissions of up to 100 kbps and operates in a
* voltage range of 5 to 27 V. All logic inputs are compatible with 3.3 V and
* 5 V supply systems. The pins MODE0 and MODE1 indicate the mode of the
* transceiver, with the transceiver being initially in sleep mode.
* An example application circuitry for the 8 pin package can be found at page
* 15 of https://www.onsemi.com/pub/Collateral/NCV7356-D.PDF.
