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?
