Message Valid Registers 1 & 2 (CAN_MVnR)

Address Offset: 160h (CAN_MV1R), 164h (CAN_MV2R)

Reset Value: 0000 0000h

These registers hold the MsgVal bits of the 32 Message Objects. By reading the MsgVal bits,

the application software can check which Message Object is valid. The MsgVal bit of a specific

Message Object can be set/reset by the application software via the IFn Message Interface
