TJA1145局部网络被错误帧(位错误)唤醒

TJA145芯片中的局部网络唤醒ID的功能:

    目前存在的疑问是:在芯片休眠之前,配置相应的寄存器中存在问题,使得芯片不仅检测相应的固定IDSignal并且检测Error Frame 并进入计数,超出计数后,错误地唤醒了芯片,使得程序运行异常;

目前休眠的操作步骤是:

1.配置局部网络唤醒的ID和信号;

2.使能局部网络唤醒,使能唤醒事件;

3.清除唤醒事件;

4.进入休眠模式

位错误导致的错误帧会唤醒收发器(不在预期内),继而唤醒芯片。

敢问各位大神,我的操作步骤哪里不对吗?

HI

I attached AN1203 for more detail information about -Application Hints - Partial Networking,please read it before do a wake up function.

你可能使用了TJA1145,换成TJA1145/FD的版本,把FD-Passive功能打开即可

我是否可以理解成:TJA1145T这款芯片并不能屏蔽由于位错误帧导致的错误计数器增加,继而唤醒MCU,只有TJA1145FD有这项功能
