The SENTDATA/NEWDATA bit indicates CAN message transmit/receive operation is completed. Set the
SENTDATA/NEWDATA bit to 0 (transmit/receive operation not completed) by a program prior to
transmitting or receiving. The SENTDATA/NEWDATA bit is not set to 0 automatically. While the
TRMACTIVE/INVALDATA bit is 1 (transmitting or storing receive data), the SENTDATA/NEWDATA bit
cannot be set to 0.
NOTES:
The TRMACTIVE/INVALDATA bit indicates that the CAN protocol controller is accessing the message slot j.
The TRMACTIVE/INVALDATA bit becomes 1 when the controller is accessing, and becomes 0 when not
accessing.
SENTDATA: The SENTDATA bit becomes 1 (transmit operation completed) when a transmit operation is
NEWDATA: The NEWDATA bit becomes 1 (receive operation completed) after the message to be stored
TRMACTIVE: The TRMACTIVE bit becomes 1 (transmitting) when a transmit operation is started. The
INVALDATA: The INVALDATA bit becomes 1 (storing receive data) while the received message is being

NEWDATA bit becomes 1 while reading the message slot, this indicates that new receive data has been
stored into the message slot while reading and the returned data contains an undefined value. In this case,
discard the data with an undefined value and then read the message slot again after setting the
NEWDATA bit to 0.
