I am using external 10MhZ clock crystal.</P><P>And I have used the OMRE(Oscillator monitor Reset Enable) feature of the MCU.</P><P>As a part of my application feature, I have to write one pattern to EEPROM after getting restart from PLL lock reset based on the status of the reset flag register.</P><P>Here I want to test my code by reproducing the scenario that causes the PLL lock reset. I am not sure how to reproduce the PLL lock reset.</P><P></P><P>Can you help me on this with any test code or other steps to test my application software.</P><P></P><P></P><P>Regards,</P><P>Vyshakh J</P></BODY></HTML> Mon, 24 Jun 2019 14:37:17 GMT https://community.nxp.com/t5/S12-MagniV-Microcontrollers/How-to-generate-PLL-lock-reset-for-S12-MagniV/m-p/963931#M16781 vyshakh_j 2019-06-24T14:37:17Z Re: How to generate PLL lock reset for S12/MagniV https://community.nxp.com/t5/S12-MagniV-Microcontrollers/How-to-generate-PLL-lock-reset-for-S12-MagniV/m-p/963932#M16782 <HTML><HEAD></HEAD><BODY><P>Hi,</P><P>Unfortunately, there is no way for the user to trigger the PLL clock monitor reset (PMRF).<BR />It is a safety feature and only for the case that the PLL is really damaged.</P><P></P><P>BR, Daniel</P></BODY></HTML> Wed, 26 Jun 2019 11:24:28 GMT https://community.nxp.com/t5/S12-MagniV-Microcontrollers/How-to-generate-PLL-lock-reset-for-S12-MagniV/m-p/963932#M16782 danielmartynek 2019-06-26T11:24:28Z
