Hi,I have a question about CAN. 


the MailBox 16 matched only 0x1f1 and the bit 16 of IMASK1 is 0,

the MaiBox 31 matched MULTIPLE CAN IDs include 1F1,and the bit 31 of IMASK1 is 1.


I use PCAN send 1F1 message per 100ms,then initialize the CAN.  Then i find the 1F1 message into the MailBOX31, Why? and the MailBox 16 seems locked.
