lpc1766 这款芯片的CAN通信如何发送“过载帧”

LPC_CAN1->CMR |= (0x01<<2);
LPC_CAN1->IER |= ((1<<0)|(1<<2)|(1<<3)); //接收数据过载中断使能

 


LPC_CAN1->GSR中的DOS标志置1时,总线上却未发现“过载帧”波形。

我仿真的时候检测can过载帧的标志位,当置位的时候并没有发现有过载帧发出的波形。

 

 

1、How do I configure this chip to make the can receiver send an overload frame?

2、an overload frame is send by hardware automatically?
