S32G2 : LLCE CAN Controller MIXED interrupt setting

skseofh — Thu, 11 Nov 2021 02:45:49 GMT

Hi~

I'm using S32G274A.

In 'LLCE firmware user guide.pdf' page 12, there is explanation on MIXED interrupt processing.(See below)

Based on this docs, I thought that FIFO can be configurable between INTERRUPT and POLLING.

But in S32DS 3.4 IDE peripheral component setting, there is no configuration on FIFO about INTR & POLLING.

I only can find CAN Controller level configuration.(See below)

How do I set INTR to some FIFOs and POLLING to some FIFOs on SAME CAN Controller?

In mixed mode, you need several HRH's each configured for either polling or
interrupt. See the Sections 3.6.2 and 3.6.3 of the CAN_LLCE Driver User Manual
for detailed information. Sections 4.116, 4.118 discuss related
Tresos configuration objects and their parameters.

Best Regards,
Platon
