Field Description
0–11
Reserved
This field is reserved.
This read-only field is reserved and always has the value 0.
12–15
TCP
Timestamp Counter Prescaler
(0x0-0xF)— 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.
NOTE: This field has Protected Write status.
NOTE: With CAN FD, timestamp generation is not supported.

00 Timestamp counter value always 0x0000
01 Timestamp counter value incremented according to TCP
