39.8.10 Timestamp Counter Value

Name: TSCV

Offset: 0x24

Reset: 0x00000000

Property: Read-only

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 14:0 – TSC[14:0] 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.
