Figure 23.10 C0TSR Register
23.1.8 CAN0 Time Stamp Register (C0TSR Register)
The C0TSR register is a 16-bit counter. The TSPRE1 and TSPRE0 bits in the C0CTLR0 register
select the CAN bus bit clock divided by 1, 2, 3 or 4 as the count source for the C0TSR register.
When data transmission or reception is completed, the value of the C0TSR register is automatically
stored into the message slot.
In loopback mode, when either data frame receive message slot or remote frame receive message
slot is available to store the message, the value of the C0TSR register is also stored into the mes-
sage slot when data reception is completed. The value of the C0TSR register is not stored when data
transmission is completed.
The C0TSR register starts a counter increment when the RESET1 and RESET0 bits in the C0CTLR0
register are set to "0".
The C0TSR register is set to "0000
CAN0 Time Stamp Register
• at the next count timing after the C0TSR register is set to "FFFF
• when the RESET1 and RESET0 bits are set to "1" (CAN module reset) by program; or
• when the TSRESET bit is set to "1" (C0TSR register reset) by program.
CAN bus bit clock =
1. Value is obtained by setting the SLEEP bit in the C0SLPR register to "1" (sleep mode exited) after
reset and supplying the clock to the CAN module.
