d12中断时的中断寄存器读出来为0x0怎么回事啊？
是在没辙了，老是会有busreset和一堆的0x0的中断，几乎所有的有效中断后都跟上一个0x0的中断，怎么回事啊，这是我的串口输出，
/// ///中为中断寄存器内容suspend suspend /// c0 /// /// 0 /// bus reset /// 1 /// /// 0 /// setu/// 2 /// /// 0 /// /// 1 /// /// 40 /// /// 0 /// p_packet bus reset /// 1 /// /// 0 /// setu/// 2 /// /// 0 /// p_packet /// 1 /// /// 0 /// /// 40 /// /// 0 /// bus reset /// 1 /// /// 0 /// setu/// 2 /// /// 0 /// /// 1 /// /// 40 /// /// 0 /// p_packet bus reset /// 1 /// /// 0 /// setu/// 2 /// /// 0 /// p_packet /// 1 /// /// 0 /// setu/// 2 /// /// 0 /// /// 2 /// /// 1 /// /// 0 /// p_packet /// 40 /// /// 0 /// bus reset /// 1 /// /// 0 /// setu/// 2 /// /// 0 /// /// 1 /// /// 40 /// /// 0 /// p_packet bus reset /// 1 /// /// 0 /// set/// 2 /// /// 0 /// up_packet /// 1 /// /// 0 /// /// 80 /// /// 0 /// suspend 枚举根本过不去，大侠帮帮我吧 |
