Read:  
For transmit buffers, anytime when TXEx flag is set (see Section 8.3.2.7, “MSCAN Transmitter  
Flag Register (CANTFLG)”) and the corresponding transmit buffer is selected in CANTBSEL (see  
Section 8.3.2.11, “MSCAN Transmit Buffer Selection Register (CANTBSEL)”).  
For receive buffers, only when RXF flag is set (see Section 8.3.2.5, “MSCAN Receiver Flag  
Register (CANRFLG)”).
