You may use bitwise AND (&) to adjust the appropriate ags. For example:
Copy Code To Clipboard
if (MsgFlag & _CANSPI_RX_OVERFLOW != 0) {
...
// Receiver overow has occurred.
// We have lost our previous message.
}
CANSPI_MASK Constants
The CANSPI_MASK constants dene mask codes. Function CANSPISetMask expects one of these as it’s argument:

const unsigned int
_CANSPI_MASK_B1 = 0,
_CANSPI_MASK_B2 = 1;
CANSPI_FILTER Constants
The CANSPI_FILTER constants dene lter codes. Functions CANSPISetFilter expects one of these as it’s
argument:
