I have configured the controller to VLPR mode at 2MHz SystemCoreClock. But this increases the execution time and hence my application gets slower. Is there any way to increase the instruction execution speed?&nbsp;</P><P></P><P>Regards,</P><P>Shrey</P></BODY></HTML> Fri, 31 Aug 2018 11:51:32 GMT https://community.nxp.com/t5/Kinetis-Microcontrollers/Execution-speed-in-VLPR-Mode/m-p/782888#M47668 shrejjjhh 2018-08-31T11:51:32Z Re: Execution speed in VLPR Mode https://community.nxp.com/t5/Kinetis-Microcontrollers/Execution-speed-in-VLPR-Mode/m-p/782889#M47669 <HTML><HEAD></HEAD><BODY><P>Hello Shrey,</P><P></P><P>In the reference manual you will find the following information in the table 5-1.&nbsp;</P><P><span class="lia-inline-image-display-wrapper" image-alt="pastedImage_2.png"><img src="https://community.nxp.com/t5/image/serverpage/image-id/68149i88FF2D4BFFB05610/image-size/large?v=v2&amp;px=999" role="button" title="pastedImage_2.png" alt="pastedImage_2.png" /></span></P><P>You can increase the speed of the clock up to 4MHz.
