You may use bitwise AND (&) to extract received message status. For example:

if (MsgFlag & _ECAN_RX_OVERFLOW != 0) {
...
// Receiver overow has occurred.
// We have lost our previous message.
}
ECAN_MASK Constants
The ECAN_MASK constants dene mask codes. The routine ECANxSetMask expect one of these as their argument:
