use the WDELAY with TMS570

Rolf Timm

Hi,

My Problem is difficult, I would the TMS570 send as master of the SPI1 with transfergroup, 2 and more. The receiver need short wait between transfergroup, but I try with WDELAY set to 63dec (0x3FHex) and enable WDEL (1 in Bit). The TMS don't insert the break, have I lost some bit enable?

Thanks for your answer

Regards, Rolf

Hi,

I have self found my problem, I read in other subscription, from the down the VCLK. Realy, by VCLK=70Mhz I can not see the break between the transferframe, but the 9,33Mhz I can see this break. Is normaly in the 70Mhz is 0x3F = 928,5ns and in the 9,33Mhz is 0x3F = 6964ns.

all the same, thanks.
