Starts UARTF data transmission.
This API function repeats the byte-level UARTF transmission from the buffer specified in argument tx_buf the number of times specified in argument tx_num. |
When performing a UARTF transmission, R_UARTFn_Start must be called before this API function is called. |
If the asynchronous serial interface LIN-UART (UARTF) is used in expansion bit mode, then store the data to send in the buffer specified by argument tx_buf, in the following format. |
"8-bit data", "Expansion bit", "8-bit data", "Expansion bit", ...
