19.5.15 MSCAN Receive Error Counter Register (CANRXERR)-MBAR + 0x091C / 0x099C
READ: Only when in Sleep Mode (SLPRQ = 1 and SLPAK = 1) or Initialization Mode (INITRQ = 1 and INITAK =1).
WRITE: Unimplemented
NOTE
Reading this register when in any other mode other than sleep or Initialization may return an incorrect
value.
NOTE
Writing to these registers when in special modes can alter the MSCAN functionality.
19.5.16 MSCAN Transmit Error Counter Register (CANTXERR)-MBAR + 0x091D/0x099D
Note: This register reflects the status of the MSCAN transmit error counter.
READ: Only when in Sleep Mode (SLPRQ = 1 and SLPAK = 1) or Initialization Mode (INITRQ = 1 and INITAK =1).
WRITE: Unimplemented
NOTE
Reading this register when in any other mode other than sleep or Initialization may return an incorrect
value.
NOTE
Writing to these registers when in special modes can alter the MSCAN functionality.
