CAN_TIMESTP

0x4001001C (0), 0x4001401C (1)

Read-only



This field carries the value of the internal CAN controller 16-bit timer value at the start or end of frame.

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.
