USIC module 2 has 4 DLR lines?
Does the latest version of DAVE support using these DLRs when mapping to hardware triggered DMAs.
Would you clarify if this is a hardware restriction, or a DAVE restriction.

Thanks,
Doug

Hi Doug,

To answer your questions:

USIC module 2 has 4 DLR lines?

Yes, as per Table 4-4 of "xmc4500_rm_v1+2_2012_12".

Does the latest version of DAVE support using these DLRs when mapping to hardware triggered DMAs.

Yes, pls choose "The requested App 'NVIC_DMA001' is sharable" when adding more than one DMAs.

Would you clarify if this is a hardware restriction, or a DAVE restriction.

Just to highlight that USIC2 is not supported in DAVE for XMC4500 AA-step device due to USIC2 FIFO silicon bug.

Best regards,
Sophia
