Hello experts!
Could you tell me the chip TCAN1044V-Q1, which behaves the same in normal mode when receiving WUP as it does in standby mode? Will it pull down the RX pin?
thanks!

您好,我们可以直接使用中文沟通。
您的意思是normal mode下,当收到WUP之后,RX会拉低吗,是这个意思吗?
事实上,WUP指的是wake-up pattern。那只有在当standby mode下,才会收到WUP唤醒pattern,从standy 到normal 转换的一个过程。
接收到WUP之后,STB由high 到low转换,本地CAN协议控制器监测RXD由高到低转换从而重新激活device进入到normal mode。
不知是否能解决您的问题。有问题再讨论。
TCAN1044也是支持远程唤醒remote wake的,是通过WUP来支持远程唤醒的。
您说的通过TX,RX两根信号线是如何实现远程唤醒的?
可以参考数据手册9.4.6.1 Remote Wake Request via Wake Up Pattern (WUP)部分的介绍。
