I'm interested in exploring whether we can use our own microcode for an application with very precise timing requirements. Is this documented anywhere?</SPAN><BR /><BR /><BR /><SPAN>Thanks</SPAN><BR /><BR /><BR /><SPAN>Simon</SPAN><BR /><DIV> </DIV></BODY></HTML> Thu, 20 Nov 2008 17:50:36 GMT https://community.nxp.com/t5/ColdFire-68K-Microcontrollers/DMA-Microcode-on-the-MCF5475/m-p/203713#M9486 SimonMarsden_de 2008-11-20T17:50:36Z Re: DMA Microcode on the MCF5475 https://community.nxp.com/t5/ColdFire-68K-Microcontrollers/DMA-Microcode-on-the-MCF5475/m-p/203714#M9487 <HTML><HEAD></HEAD><BODY>Simon,<BR /><BR />There are no tools available to enable users to write and test their own microcode.&nbsp; Please refer to this thread for more details:<BR /><BR /><A href="http://forums.freescale.com/freescale/board/message?board.id=CFCOMM&amp;message.id=2176&amp;query.id=70624#M2176" target="test_blank">http://forums.freescale.com/freescale/board/message?board.id=CFCOMM&amp;message.id=2176&amp;query.id=70624#M2176</A><BR /><BR />-mnorman<BR /><DIV></DIV></BODY></HTML> Fri, 21 Nov 2008 00:25:07 GMT https://community.nxp.com/t5/ColdFire-68K-Microcontrollers/DMA-Microcode-on-the-MCF5475/m-p/203714#M9487 mnorman 2008-11-21T00:25:07Z Re: DMA Microcode on the MCF5475 https://community.nxp.com/t5/ColdFire-68K-Microcontrollers/DMA-Microcode-on-the-MCF5475/m-p/203715#M9488 <HTML><HEAD></HEAD><BODY>Thanks for the update.<BR /><BR /><BR />Simon<BR /><DIV></DIV></BODY></HTML> Fri, 21 Nov 2008 02:00:09 GMT https://community.nxp.com/t5/ColdFire-68K-Microcontrollers/DMA-Microcode-on-the-MCF5475/m-p/203715#M9488 SimonMarsden_de 2008-11-21T02:00:09Z
