hi,
i'm programming a mc9s08qe8 with codewarrior.
i use device initialization to configure the chip.
i'm working with 1MHz bus clock in FEI mode. i've all periperals disabled.
i've enable "stop instruction enabled".
i'd like to put the uC in stop3 mode, in the main there is "asm STOP;".
it goes in stop but the uC absorbs 40uA insted of 1uA...
i don't know how i can reduce the current... i think there is something that i've to switch off!
someone can help me?

See this https://community.freescale.com/message/96506#96506. Make sure you are turning off ICSIRCLK.

 

As an aside, every input pin should be at ground or vcc of the chip. Every output pin should not be loaded.

 

Did you disable all your peripherals and and THEN shut the clocks off to them?
