The internal/external Timestamp Counter value is captured on
start of frame (both Receive and Transmit). When MCAN_TSCC.TSS = 1, the Timestamp
Counter is incremented in multiples of CAN bit times [ 1…16 ] depending on the
configuration of MCAN_TSCC.TCP. A wrap around sets interrupt flag MCAN_IR.TSW. Write
access resets the counter to zero.
When MCAN_TSCC.TSS = 2, TSC reflects the external Timestamp
Counter value. Thus a write access has no impact.
Note: A “wrap around” is a change of the Timestamp Counter value from non-zero to zero
not caused by write access to MCAN_TSCV.
