DMA CRC issue

Open michalelektryk opened this issue 2 years ago • 1 comments

It's not exactly specified in docs if htere's one CRC unit for all DMA channels or there's one per channel. From datasheet it seems there's one per channel but from from SDK it seems there's one for all DMA units. Which one is correct?

There is one module in the hardware. This is clear in datasheet and SDK.

Section 2.5.5.2 is misleading, but the register API is clear in Table 146 (SNIFF_CTRL::DMACH).
