Register 36: CAN Message 1 Valid (CANMSG1VAL), offset 0x160
Register 37: CAN Message 2 Valid (CANMSG2VAL), offset 0x164
The CANMSG1VAL and CANMSG2VAL registers hold the MsgVal bits of the 32 message objects.
By reading these bits, the CPU can check which message object is valid. The message value of a
specific message object can be changed with the CAN IFn Message Control (CANIFnMCTL)
register.
The CANMSG1VAL register contains the MsgVal bit of the first 16 message objects in the message
RAM; the CANMSG2VAL register contains the MsgVal bit of the second 16 message objects in
the message RAM.

Preliminary
Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
Message Valid Bits
(of all message objects)
0: This message object is not configured and is ignored by the message
handler.
1: This message object is configured and should be considered by the
message handler.
