For my final application I will need to use SPI0 and I thought this would be an easy change with PE in KDS 3.2.0. However, PE does not let me select a HW buffer of 8 (FIFO enabled)&nbsp; for SPI0. It says, "ERROR: The device doesn't support this setting!" I've reviewed the Reference Manual and I have not found anything indicating that this feature is not available for SPI0. Is there something I'm overlooking or is this a bug in PE?</P></BODY></HTML> Sun, 08 Oct 2017 03:58:36 GMT https://community.nxp.com/t5/Kinetis-Microcontrollers/KL46-SPI0-FIFO/m-p/701144#M43120 eric_b 2017-10-08T03:58:36Z Re: KL46 SPI0 FIFO https://community.nxp.com/t5/Kinetis-Microcontrollers/KL46-SPI0-FIFO/m-p/701145#M43121 <HTML><HEAD></HEAD><BODY><P>Hi Eric,</P><P>I am sorry to tell you that the SPI0 of KL46 does not 'include a 4-deep FIFO'.</P><P><span class="lia-inline-image-display-wrapper" image-alt="SPI1 includes a 4-deep FIFO.png"><img src="https://community.nxp.com/t5/image/serverpage/image-id/13308iEBED29D00DFF50D5/image-size/large?v=v2&amp;px=999" role="button" title="SPI1 includes a 4-deep FIFO.png" alt="SPI1 includes a 4-deep FIFO.png" /></span></P><P>Best Regards,</P><P>Robin</P><P style="min- padding: 0px;">&nbsp;</P><P>-----------------------------------------------------------------------------------------------------------------------<BR />Note: If this post answers your question, please click the Correct Answer button.
