TI中文支持网请问28335的CAN模块中，邮箱接收到的帧标识符，怎么读取?
Forrest：
通过读取MSGID寄存器，来获取Message identifier

MSGID不是用来设置接收标识符的吗？因为我要设置掩码位，一个邮箱读多个帧的，那读MSGID是不是返回当前帧的标识符，读下一帧的时候MSGID不用重设吗？

HI，What is the relationship between the IDE, AME, AAM bits of MSGID and MSGID settings, such as MSGID=0xd5555333, do I still need to set the IDE and other bits, why sometimes the extended frame format is given, the program is processed according to the standard frame?
