Due to the 32KHz XTAL<BR />start up time, 40KHz RingOSC is selected as the default clock source during SoC power<BR />up. Once the 32KHz XTAL starts up, the clock source will be switched to it<BR />automatically and the 40KHz RingOSC will be shut off. If the 32KHz XTAL stops in<BR />some case, the 40KHz RingOSC will be enabled and selected as the source. The enable/<BR />disable of the 40KHz RingOSC and the clock source switching is done automatically in<BR />HW and there is no programmable register for SW to select the clock source. There is<BR />only one read-only register to show the current clock source.<BR />-------------------------------------------------------------------------------------------------------------------</P><P></P><P>Can we use TEMPMON without 32 KHz RTC?<BR />If yes,<BR />1) Do we need any special setting?<BR />2) Please also let me know if you have any caveats.</P><P></P><P>Best Regards,</P></BODY></HTML> Wed, 07 Jun 2017 05:53:27 GMT https://community.nxp.com/t5/i-MX-Processors/i-MX7D-Regarding-TEMPMON-without-RTC-XTAL/m-p/677052#M104450 tomohisa_sakamo 2017-06-07T05:53:27Z Re: i.MX7D Regarding TEMPMON without RTC XTAL　 https://community.nxp.com/t5/i-MX-Processors/i-MX7D-Regarding-TEMPMON-without-RTC-XTAL/m-p/677053#M104451 <HTML><HEAD></HEAD><BODY><P>Hi Tomohisa</P><P></P><P>&gt;Can we use TEMPMON without 32 KHz RTC?<BR />yes</P><P></P><P>&gt;1) Do we need any special setting?</P><P>no</P><P><BR />&gt;2) Please also let me know if you have any caveats.</P><P>there are no caveats for using TEMPMON without 32 KHz RTC</P><P></P><P>Best regards<BR />igor<BR />-----------------------------------------------------------------------------------------------------------------------<BR />Note: If this post answers your question, please click the Correct Answer button.
