On all S12(X) devices in order to enter Stop mode, two instructions must be executed:</P><P></P><P> asm ANDCC #0x7F; //clear S bit in CPU Condition Code Register (CCR) - enable the stop mode.</P><P></P><P> asm STOP;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // stop mode</P></BODY></HTML> Fri, 17 Apr 2015 09:10:14 GMT https://community.nxp.com/t5/S12-MagniV-Microcontrollers/sleep-mode/m-p/414510#M11187 iggi 2015-04-17T09:10:14Z Re: sleep mode https://community.nxp.com/t5/S12-MagniV-Microcontrollers/sleep-mode/m-p/414511#M11188 <HTML><HEAD></HEAD><BODY><P>Really thanks for your reply. </P><P></P><P>We need to exist the STOP mode by external interrupt. E.g. nXIRQ or IRQ. Can we wake up the MCU by any internal interrupt? Let say timer?</P><P></P><P>I want to implement a periodical mode for power saving.</P></BODY></HTML> Fri, 17 Apr 2015 09:28:42 GMT https://community.nxp.com/t5/S12-MagniV-Microcontrollers/sleep-mode/m-p/414511#M11188 monstor 2015-04-17T09:28:42Z
