Hi, 

In the hardware maunal, pg, 821;
”Change the UMask bit while Init bit of the CAN control register (CTRLR) is "1" or while MsgVal bit is "0".”

https://www.infineon.com/dgdl/Infineon-MB91580M_S_Series_32-bit_Microcontroller_FR_Family_FR81S_Hard...


If we cannot meet this sequence, please let me know possiblity of unexpected error, fault and so on, if possible.

In our application program, we change the UMask bit when Init bit = 0 and MsgVal bit = 1.
But we have confirmed that behavior is no ploblem.

I understand that it might be cause unexpected error but we wouldn't like to change SW design if there is no problem.

Please let me know if you have any query.

Best regards,
