Chapter 12 Freescale’s Controller Area Network (S08MSCANV1)
Section 12.3.1, “MSCAN Control Register 0
read the time stamp after the respective transmit buffer has been flagged empty.
The timer value, which is used for stamping, is taken from a free running internal CAN bit clock. A timer
overrun is not indicated by the MSCAN. The timer is reset (all bits set to 0) during initialization mode. The
CPU can only read the time stamp registers.
Read: Anytime when TXEx flag is set (see
(CANTFLG)”) and the corresponding transmit buffer is selected in CANTBSEL (see
“MSCAN Transmit Buffer Selection Register
