Freescale’s Scalable Controller Area Network (S12MSCANV3)
In cases of more than one buffer having the same lowest priority, the message buffer with the lower index
number wins.
1. Read: Anytime when TXEx flag is set (see
8.3.3.5
If the TIME bit is enabled, the MSCAN will write a time stamp to the respective registers in the active
transmit or receive buffer right after the EOF of a valid message on the CAN bus (see
“MSCAN Control Register 0
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.
