• MTIMESTAMPx: Timestamp
This field represents the internal CAN controller 16-bit timer value.
If the TEOF bit is cleared in the CAN_MR register, 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
register. If the TSTP mask in the CAN_IMR register is set, an interrupt is generated while TSTP flag is set in the CAN_SR regis-
ter. This flag is cleared by reading the CAN_SR register.
Note:
The CAN_TIMESTP register is reset when the CAN is disabled then enabled thanks to the CANEN bit in the
CAN_MR.
