| 19:16 | TCP | R/W | 0h | 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. Note: With CAN FD an external counter is required for timestamp generation. MCAN_TSCC[1-0] TSS = 2'b10 |
| 15:2 | NU20 | R | 0h | Reserved |
| 1:0 | TSS | R/W | 0h | Timestamp Select 2'b00 = Timestamp counter value always 0 2'b01 = Timestamp counter value incremented according to the MCAN_TSCC[19-16] TCP field 2'b10 = External timestamp counter value used 2'b11 = Same as 2'b00 |
