I'm e.g. missing hold time ALE Low to Address valid and also Data valid from CS going high. Where can I find it?<BR />The EZPORT timing is given much better within the family datasheets.<BR /><BR />Thanks<BR />FB</BODY></HTML> Wed, 27 Jun 2012 05:51:09 GMT https://community.nxp.com/t5/Kinetis-Microcontrollers/Kinetis-Flexbus-timing/m-p/175568#M1480 Burba 2012-06-27T05:51:09Z Re: Kinetis Flexbus timing https://community.nxp.com/t5/Kinetis-Microcontrollers/Kinetis-Flexbus-timing/m-p/175569#M1481 <HTML><HEAD></HEAD><BODY>Now I know why I even did not get any aswer from freescale. I've done some measurements by myself and found that the adress hold time from ALE going Low is 0 or even little bit negative. That mean that you must use one additional waitstate for ALE for multiplexed flexbus write acces which is a very bad situation and totally waste of performance. With a very fast RAM you waste about 30% of flexbus throughput. I just wonder if the same problem exists on other Cortex M3 devices from other brands.</BODY></HTML> Mon, 03 Sep 2012 21:08:09 GMT https://community.nxp.com/t5/Kinetis-Microcontrollers/Kinetis-Flexbus-timing/m-p/175569#M1481 Burba 2012-09-03T21:08:09Z Re: Kinetis Flexbus timing https://community.nxp.com/t5/Kinetis-Microcontrollers/Kinetis-Flexbus-timing/m-p/175570#M1482 <HTML><HEAD></HEAD><BODY><P>try to send Service Request with high priority</P></BODY></HTML> Thu, 06 Sep 2012 12:47:39 GMT https://community.nxp.com/t5/Kinetis-Microcontrollers/Kinetis-Flexbus-timing/m-p/175570#M1482 luke_8 2012-09-06T12:47:39Z Re: Kinetis Flexbus timing https://community.nxp.com/t5/Kinetis-Microcontrollers/Kinetis-Flexbus-timing/m-p/175571#M1483 <HTML><HEAD></HEAD><BODY><P>Hi Helmut, please check my answer in your inbox.</P></BODY></HTML> Mon, 22 Oct 2012 21:21:33 GMT https://community.nxp.com/t5/Kinetis-Microcontrollers/Kinetis-Flexbus-timing/m-p/175571#M1483 apanecatl 2012-10-22T21:21:33Z
