** Changes the CAN FD transceiver mode for specified channel.
** In the target environment, TJA1145 is mounted. This transceiver transits to
** the 'Standby' mode after starting by turning the power on. So its mode should
** be changed to the 'Normal' mode to communicate via CAN.

** \param [in] c CAN FD channel number (0-).
** \param [in] m CAN FD transceiver mode
** 1(001B) : Sleep mode
** 4(100B) : Standby mode
** 7(111B) : Normal mode
