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.
New Data
0: No new data has been written into the data portion of this message
object by the message handler since the last time this flag was cleared
by the CPU.
1: The message handler or the CPU has written new data into the data
portion of this message object.
Message Lost
0 : No message was lost since the last time this bit was reset by the
CPU.
1: The message handler stored a new message into this object when
NewDat was set; the CPU has lost a message.
This bit is only valid for message objects with the Dir bit in the
CANIFnARB2 register set to 0 (receive).
Interrupt Pending
0: This message object is not the source of an interrupt.
1: This message object is the source of an interrupt. The interrupt
identifier in the CAN Interrupt (CANINT) register will point to this
message object if there is not another interrupt source with a higher
priority.
Use Acceptance Mask
0: Mask ignored.
1: Use mask (Msk, MXtd, and MDir) for acceptance filtering.
