楼主你好。
你可以看下KEA的RM,
33.4.3.1 Data sampling technique
The UART receiver uses a 16× baud rate clock for sampling. The oversampling ratio is
fixed at 16. The receiver starts by taking logic level samples at 16 times the baud rate to
search for a falling edge on the RxD serial data input pin. A falling edge is defined as a
logic 0 sample after three consecutive logic 1 samples.
你可以看做这个也是一个新的同步。
其实KEA的LIN是满足LIN 协议标准的,所以你可以放心使用。
你可以用试试,大量测试,如果有问题再探讨。
