CAN过滤器如何在Pictus上工作

我在SPC560P上测试CAN过滤功能，但我不清楚CAN Mask如何工作。

配置如下：
Rx ID = 0，Rx Individual Mask = 0xFFFFFF8; BCC = 1;从我的理解，然后CAN节点可以从0到7接收ID，但不能，只能仍然可以接收ID = 0;停下来
检查BUF00 Rx标志;
但是，当我设置Rx Individual Mask = 0时;可以接收所有CAN ID（在BUF00 Rx标志处停止检查）;
那么，CAN ID掩码如何工作？
-----------------
CAN_0.RXIMR [0] .R = 0xFFFFFFF8; / * Rx个人面具* /
CAN_0.BUF [0] .ID.B.STD_ID = 0x0; / * Rx ID = 0 * /
/ *检查ID接收* /
if（1 == CAN_0.IFRL.B.BUF00I）{

CAN_0.IFRL.B.BUF00I = 1;
// rx完成了

}

I am testing CAN filtering Function on SPC560P,But am not clear about how CAN Mask working.

Configure as following:
Rx ID =0, Rx Individual Mask = 0xFFFFFF8; BCC = 1; From my understanding, then the CAN Node can Receive ID from 0  to 7, but cannot , only still can receive ID = 0; stop at
BUF00 Rx Flag checked;
But , when I set Rx Individual Mask = 0; all CAN ID can be received (stop at BUF00 Rx Flag checked);
So, How the CAN ID Mask Working?
-----------------
  CAN_0.RXIMR[0].R = 0xFFFFFFF8; /*Rx Individual Mask*/
   CAN_0.BUF[0].ID.B.STD_ID = 0x0; /*Rx ID = 0*/
/*Check ID Receive*/
  if(1== CAN_0.IFRL.B.BUF00I){

    CAN_0.IFRL.B.BUF00I = 1;
     // rx completed
