33.7.10 Timestamp Counter Value

Note:
  1. A write access to TSCV while in internal mode clears the Timestamp Counter value. A write access to TSCV while in external mode has no impact.
  2. A “wrap around” is a change of the Timestamp Counter value from non-zero to zero not caused by the write access to TSCV.

Bits 15:0 – TSC[15:0] Timestamp Counter

The internal Timestamp Counter value is captured on start of frame (both Rx and Tx). When TSCC.TSS = 0x1, the Timestamp Counter is incremented in multiples of CAN bit times [1...16] depending on the configuration of TSCC.TCP. A wrap around sets interrupt flag IR.TSW.
