How to know the current CAN Transmit errors and receive errors?

[Saga]

Hi to all, i would like to know the current number of errors and there is 2 registers called:

CANTXERR (MSCAN Transmit Error Counter)
CANRXERR (MSCAN Receive Error Counter)

Both registers have the number of transmision and reception errors, but the datasheet says:

Read: Only when in sleep mode (SLPRQ = 1 and SLPAK = 1) or initialization mode (INITRQ = 1 and
INITAK = 1)

NOTE
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.

And I can't go back to initialization mode or go to sleep mode (it's not up to me).

Is there another way to know the current errors?

Thank you very much...

you can't read the number of errors.

you can check these bits:

CANRFLG_OVRIF         
CANRFLG_TSTAT0              
CANRFLG_TSTAT1             
CANRFLG_RSTAT0               
CANRFLG_RSTAT1          

they are readable anytime
