CAN0 Transmit Error Count Register
The C0TSR register is a 16-bit counter. The TSPRE0 and TSPRE1 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.
The C0TSR register starts a counter increment when the RESET0 and RESET1 bits in the C0CTLR0
register are set to "0".
The C0TSR register is set to "0000
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.
In an error active or an error passive state, the count value of a transmission error is stored into the
C0TEC register. The counter is decremented when the CAN module has transmitted data as ex-
pected or is incremented when an transmit error occurs.
In a bus-off state, an indeterminate value is stored into the C0TEC register. The C0TEC register is
set to "00

1. Value is obtained by setting the SLEEP bit in the C0SLPR register to "1" (sleep mode exited) and
• at the next count timing after the C0TSR register is set to "FFFF
• when the RESET0 and RESET1 bits are set to "1" (CAN module reset) by program, or
• when the TSRESET bit is set to "1" (C0TSR register reset) by program.
