1. Read: Always reads zero in normal system operation modes
21.3.2.14 MSCAN Receive Error Counter (CANRXERR)
This register reflects the status of the MSCAN receive error counter.
1. Read: Only when in sleep mode (SLPRQ = 1 and SLPAK = 1) or initialization mode (INITRQ = 1 and INITAK = 1)

Writing to this register when in special system operating modes can alter the
MSCAN functionality.
Reading this register when in any other mode other than sleep or
initialization mode may return an incorrect value. For MCUs with dual
CPUs, this may result in a CPU fault condition.
Writing to this register when in special modes can alter the MSCAN
functionality.
