Make sure you are turning off ICSIRCLK.</P><P>&nbsp;</P><P>As an aside, every input pin should be at ground or vcc of the chip. Every output pin should not be loaded.</P><P>&nbsp;</P><P>Did you disable all your peripherals and and THEN shut the clocks off to them?</P><P>&nbsp;</P><P>&nbsp;</P></BODY></HTML> Wed, 07 Mar 2012 04:34:16 GMT https://community.nxp.com/t5/8-bit-Microcontrollers/MC9S08-in-stop-mode/m-p/213099#M18382 PG1 2012-03-07T04:34:16Z
