Caution The time stamp function using the TSLOCK bit stops toggle of the TSOUT signal by receiving a data
frame in message buffer 0. Therefore, message buffer 0 must be set as a receive message buffer.
Since a receive message buffer cannot receive a remote frame, toggle of the TSOUT signal cannot be
stopped by reception of a remote frame. Toggle of the TSOUT signal does not stop when a data
frame is received in a message buffer other than message buffer 0.
For these reasons, a data frame cannot be received in message buffer 0 when the CAN module is in
the normal operation mode with ABT, because message buffer 0 must be set as a transmit message
buffer. In this operation mode, therefore, the function to stop toggle of the TSOUT signal by the
TSLOCK bit cannot be used.
