(b) UART Buffer Transmission
The LIN/UART module (in UART mode) has a maximum of nine bytes of UART buffers, and thus it is capable of
performing continuous transmissions through the use of UART buffers.
Figure 17-25 shows the UART buffer transmission operation in the LIN/UART module (in UART mode). Table
17-19 shows the UART buffer transmission processing.
