Hello.

I'm using AM-3517 and DM-3730 mcspi.

How to insert delay cycle between transferring bytes ?

AM1707 and AM1808's SPI controller have SPIFMTn.WDELAY bits.

Is there counterpart of this on AM-3517 and DM-3730 mcspi ?

Hi Takafumi,

The DM3730 SPI controller has not SPIFMTn.WDELAY bits but has possibility to set delay between SPI words. You can find detailed description in the TRM chapters: 20.3 McSPI Functional Interface and 20.5 McSPI Functional Description:

Hi Tsvetolin,

Thunks for your reply.

I checked up this trm and other data sheets available at TI's web site.

But could not find out the solution.
