Here, i clocked ADC for 2Mhz&nbsp;. The problem is I cannot observe the count value properly as it varies too much. My count should be a stable one as I'm generating a CAN message with&nbsp; this count &nbsp;value. If such fluctuations happen, my CAN message will aslo vary leading to the publishing of error messages. Any one who can help me out with this issue?</P><P>&nbsp;</P><P>Thankyou in advance.&nbsp;</P></BODY></HTML> Fri, 15 Apr 2011 11:13:06 GMT vishaka_maithil 2011-04-15T11:13:06Z ADC count issue for XS128 controller https://community.nxp.com/t5/S12-MagniV-Microcontrollers/ADC-count-issue-for-XS128-controller/m-p/198537#M7968 <HTML><HEAD></HEAD><BODY><P>Dear friends,</P><P>&nbsp;</P><P>I am using mc9s12xs128 controller (16-bit)&nbsp; and the crystal is&nbsp; at 16Mhz .I have an analog input for which i'm monitoring&nbsp; ADC count.
