Hi qiansan,

Here you can see the LIN_LPUART_DRV_IRQHandler is used to for LIN driver:

However, in the execution process of the main function, I did not find the part of serial port interrupt service function registration, nor did I find the part of serial port interrupt enable. If Lin communication uses serial port interrupt to receive data, where is the interrupt enabled and where is the interrupt service function registered?

If the Lin node enters the sleep mode, does it adjust some functions of the serial port to the low-power mode or turn it off? I would like to ask what functions are adjusted to reduce the power consumption if the node enters the sleep mode compared with the normal mode
