CHAPTER 20 LIN-UART
Communication procedure
Communication starts at arbitrary timing from the transmission side when the transmission data is
provided. When the transmission data is received at the reception side, ANS (per one byte in example) is
returned periodically. Figure 20.7-12 shows an example of the bi-directional communication flowchart.
