DCAN IF3 Interrupt Line Enable from DCAN Peripheral Side

Hello Support,

In the TRM spnu499.pdf, I see the following statement:

23.11 Interrupt Functionality

Interrupts can be generated on two interrupt lines:

1. DCAN0INT line

2. DCAN1INT line

These lines can be enabled by setting IE0 and IE1 bits respectively in CAN Control Register.

The DCAN provides three groups of interrupt sources: Message Object Interrupts, Status Change

Interrupts and Error Interrupts.( see

Figure 23-13 and Figure 23-14

)

In the TMS470LS3137 Datasheet I see there is a DCANx IF3 Interrupt Line.

How do I enable the above mentioned DCANx IF3 Interrupt Line on the DCANx Peripheral Side [similar to IE0 and IE1].

I am assuming DEx bits only affects the DMAREQ Lines from DCAN to DMA.

Also, in the TRM as shown in the above section, there is no mentioned of DCANx IF3 Interrupt Source.

Please help me understand the DCANx IF3 Interrupt Line better with more details.

Thank you.

Regards

Pashan
