DM8148 Multiplexed C674x Event Sources

RandyP
Guru* 84110 points

In the DM8148 datasheet sprs647c on page 221 of 375, Table 7-19 describes several interrupt sources that can apparently be selected through a multiplexer to generate interrupts to the C674x DSP core.

After looking through that datasheet and the TRM, I cannot find anything that describes the logic behind this table or how to use these event sources.

How are these used? For example, how could I route TINT8 or WDTINT0 to the C674x using this feature?

Regards,
RandyP

    RandyP,

    I couldn't find too. I think its a miss in the TRM document.

    However, in reality we have control module registers which allow the mux selection for selecting the interrupt routing to the processor cores (C67x, M3..etc).

    I have pinged the document owners about it.

    Regards
