48.6.9 MCAN Timestamp Counter Configuration Register
For a description of the Timestamp Counter see Timestamp Generation.
With CAN FD, an external counter is required for timestamp generation (TSS = 2).

Bits 19:16 – TCP[3:0] Timestamp Counter Prescaler
Configures the timestamp and timeout counters time unit in multiples of CAN bit times [ 1…16 ]. The actual interpretation by the hardware of this value is such that one more than the value programmed here is used.
Bits 1:0 – TSS[1:0] Timestamp Select
| Value | Name | Description |
|---|---|---|
| 0 | ALWAYS_0 | Timestamp counter value always 0x0000 |
| 1 | TCP_INC | Timestamp counter value incremented according to TCP |
| 2 | EXT_TIMESTAMP | External timestamp counter value used |
| 3 | ALWAYS_0 | Timestamp counter value always 0x0000 |
