Question on EDMA ACNT

Hi there,

I have a quick question on EDMA.

On the page 74 of spru966b.pdf, the example said there are 256 words (I supposed 2 bytes word) to be copied. But on the next page, ACNT=0x100h, BCNT = 0x1h and CCNT = 0x1h, which means there are ACNT*BCNT*CCNT = 256 bytes will be copied. I am so confused on it.

    Hi Fan

    This is a typo. Sorry for the confusion. I have submitted a document ticket to get this fixed.

    It should be 256 bytes (in the text)  --> Typically for c6000 processors a "word"  implies 32 bit/4 bytes. So for 256 words transfer, the ACNT should've been 1024 bytes/ 0x400h.
