1. I want to know whether it is only necessary to call the SPI instruction to set the GO_LPOFF bit to 1 when setting the FS4500 sleep mode. After the SPI instruction is written successfully, the code running phenomenon will stop executing the subsequent code.
[GW]看我标出来的箭头两个方式进入sleep的模式。


DFS要不要进入看上面的SELECTpin设定
2. Given that the INH pin of 1145 transceiver is connected to IO_0 of FS4500, if you want to use 1145 transceiver to wake up FS4500 from LPOFF, do you only need to use the host computer to send CAN packet to wake up 1145 transceiver? The INH pin of the 1145 transceiver automatically affects the IO_0 of the FS4500 to wake up the FS4500. Can the subsequent code be continued, or does another method be required to wake up the FS4500?
[gw]你是想通过1145的INHpin唤醒FS45吗从LPOFF模式?可以看下面圈出来的唤醒方式,如果是通过IO唤醒在进入sleep之前就要设定好,你要看不同模式下1145 INH的状态是不是符合唤醒的要求从而决定要不要1145 进入低功耗模式,逻辑很清楚需要您自己去设计这个功能
