IT CAN Management
The different interrupts are:
Transmission interrupt,
Reception interrupt,
Interrupt on error (bit error, stuff error, crc error, form error, acknowledge error),
Interrupt when Buffer receive is full,
Interrupt on overrun of CAN Timer.

CAN Controller Interrupt Structure
To enable a transmission interrupt:
Enable General CAN IT in the interrupt system register,
Enable interrupt by message object, EICHi,
Enable transmission interrupt, ENTX.
To enable a reception interrupt:
Enable General CAN IT in the interrupt system register,
Enable interrupt by message object, EICHi,
