CAN Module: abort acknowledge

Hi,

 

on the BF548 CAN module, how can I distiguish between

"arbitration lost", which is not an error condition, and

"no acknowledge", which is an error ?

 

As the AAx bits and AAIS / AAIF bits are set in both

cases, I see no means to find out, if there was an error

or just a lost arbitration. Or is the TRSx bit not reset, if

arbitration was lost (assuming single shot mode is off) ?

 

Regards,

Gerhard
