Configure a start bit of transmission after configuring the data buffer. It enables the start bit to be<br />

transmitted after time that a bus is free is properly maintained.<br />

Transmitting the first data bit subsequent to the start bit generates a transfer interrupt. It indicates<br />

that the next data can be set to a transmit buffer. The ACK bit is sent after a byte of data (8 bit) and<br />

the EOM bit are transmitted, and then the ACK response is detected.<br />

The data transmission per byte continues until the data including the EOM bit that indicates “1” is<br />

stored in the transmit buffer. If its transmission is completed, a transmit completion interrupt is<br />

generated.<br />

If an error is generated during transmission, an error interrupt is generates to stop transmission.<br />

Even if reception is enabled, no reception is executed during transmission.<br />

Wait for bus to be free<br />
