CAN Controller
22.14.10 MSCAN08 Receive Error Counter Register
22.14.11 MSCAN08 Transmit Error Counter Register
Technical Data

NOTE:
Address:
Address:
This register reflects the status of the MSCAN08 receive error counter.
The register is read only.
This register reflects the status of the MSCAN08 transmit error counter.
The register is read only.
For both error counters, there is no hardware synchronization between
the write accesses to those registers from the MSCAN08 side and the
read accesses by the CPU. It is the user’s responsibility to verify that a
stable value has been read by executing a second validation read and
comparing the two values.
