I also can confirm the presence of pwm pulses in stop mode. I have seen this before in my other projects using atmega pwm. Even though the compare value is zero, there will be one timer clock pulse at the compare output pin(s) every overflow. What I did is disconnect the compare output from the port pins. So in the code, this change worked for me:
cbi(PORTD,5);
cbi(DDRB,1); cbi(DDRB,2); // change direction to input, disconnect output compare(s)
}
else
{sbi(PORTD,5);
sbi(DDRB,1); sbi(DDRB,2);} // restore direction to output
The change is not needed since the SD of the IR2184 is already being used.
