Figure 27.2 shows an Operating Example during Header Field Transmission in master mode. Figures 27.3 and
27.4 show Examples of Header Field Transmission Flowchart.
During header field transmission, the hardware LIN operates as follows:
(1) When 1 is written to the TSTART bit in the TRACR register for timer RA, a “L” level is output from the
(2) When timer RA underflows, the TXD0 pin output is inverted and the SBDCT flag in the LINST register is
(3) The hardware LIN transmits “55h” via UART0.
(4) After the hardware LIN completes transmitting “55h”, it transmits an ID field via UART0.
(5) After the hardware LIN completes transmitting the ID field, it performs communication for a response
