Figure 21-19: ECAN™ Event Interrupts

21.11.3.1 TRANSMIT BUFFER INTERRUPT

The message buffers 0 to 7 that are configured for message transmission set the Transmit Buffer

Interrupt (TBIF) bit (CiINTF<0>) after the CAN message is transmitted. The ICODE<6:0> bits

(CiVEC<6:0>) indicate the specific message buffer that generated the transmit buffer interrupt.

Transmit buffer interrupt must be cleared in the Interrupt Service Routine (ISR) by clearing the

TBIF bit.
