Mask Extended Identifier
0 = The extended identifier bit (IDE) has no effect on the acceptance filtering.
1 = The extended identifier bit (IDE) is used for acceptance filtering.
Note:
When 11-
bit (“standard”) Identifiers are used for a Message Object, the identifiers
of received Data Frames are written into bits ID28 to ID18 (CAN_IFn_ARB2[12:2]). For
acceptance filtering, only these bits together with mask bits Msk28 to Msk18
(CAN_IFn_MASK2[12:2]) are considered.

MDir
Mask Message Direction
0 = The message direction bit (Dir (CAN_IFn_ARB2[13])) has no effect on the acceptance
filtering.
1 = The message direction bit (Dir) is used for acceptance filtering.
