CAN Controller Timing Modes
Timestamping Mode
Using the free running 16-bit internal timer, the CAN controller can be set in one of the two fol-
lowing timing modes:
Timestamping Mode is enabled by clearing the TTM bit in the CAN_MR register. Time Triggered
Mode is enabled by setting the TTM bit in the CAN_MR register.
Each mailbox has its own timestamp value. Each time a message is sent or received by a mail-
box, the 16-bit value MTIMESTAMP of the CAN_TIMESTP register is transferred to the LSB bits
of the CAN_MSRx register. The value read in the CAN_MSRx register corresponds to the inter-
nal timer value at the Start Of Frame or the End Of Frame of the message handled by the
mailbox.

• Timestamping Mode: The value of the internal timer is captured at each Start Of Frame or
