36.8.8 CAN Timestamp Register
Name: CAN_TIMESTP
Address: 0xFFFAC01C
Access: Read-only
• MTIMESTAMPx: Timestamp
This field represents the internal CAN controller 16-bit timer value.
If the TEOF bit is cleared in the CAN_MR, the internal Timer Counter value is captured in the MTIMESTAMP field at each
start of frame. Else the value is captured at each end of frame. When the value is captured, the TSTP flag is set in the
CAN_SR. If the TSTP mask in the CAN_IMR is set, an interrupt is generated while TSTP flag is set in the CAN_SR. This
flag is cleared by reading the CAN_SR.
Note: The CAN_TIMESTP register is reset when the CAN is disabled then enabled thanks to the CANEN bit in the CAN_MR.
