Interrupt Enable
| RIE | Receiver Interrupt Enable. When the Receive Buffer Status is ‘full’, the CAN Controller requests the respective interrupt. |
| TIE1 | Transmit Interrupt Enable for Buffer1. When a message has been successfully transmitted out of TXB1 or Transmit Buffer 1 is accessible again (e.g. after an Abort Transmission command), the CAN Controller requests the respective interrupt. |
| EIE | Error Warning Interrupt Enable. If the Error or Bus Status change (see Status Register), the CAN Controller requests the respective interrupt. |
| DOIE | Data Overrun Interrupt Enable. If the Data Overrun Status bit is set (see Status Register), the CAN Controller requests the respective interrupt. |
| WUIE | Wake-Up Interrupt Enable. If the sleeping CAN controller wakes up, the respective interrupt is requested. |
| EPIE | Error Passive Interrupt Enable. If the error status of the CAN Controller changes from error active to error passive or vice versa, the respective interrupt is requested. |
| ALIE | Arbitration Lost Interrupt Enable. If the CAN Controller has lost arbitration, the respective interrupt is requested. |
| BEIE | Bus Error Interrupt Enable. If a bus error has been detected, the CAN Controller requests the respective interrupt. |
| IDIE | ID Ready Interrupt Enable. When a CAN identifier has been received, the CAN Controller requests the respective interrupt. |
| TIE2 | Transmit Interrupt Enable for Buffer2. When a message has been successfully transmitted out of TXB2 or Transmit Buffer 2 is accessible again (e.g. after an Abort Transmission command), the CAN Controller requests the respective interrupt. |
| TIE3 | Transmit Interrupt Enable for Buffer3. When a message has been successfully transmitted out of TXB3 or Transmit Buffer 3 is accessible again (e.g. after an Abort Transmission command), the CAN Controller requests the respective interrupt. |
| RESERVED | Reserved. Read value is undefined, only zero should be written. |
