Fast PWM mode not working

[donothingloop]

Hi,

It seems that there is an issue with Fast PWM mode at least on the ATMEGA1280 core.

#include <avr/io.h>

void main(void) {
        DDRH = 255;
        TCCR4A |= (1<<COM4A0) | (1<<COM4A1) | (1<<WGM41);
        TCCR4B |= (1<<WGM43) | (1<<WGM42);
        TCCR4B |= (1<<CS42) | (1<<CS40);
        ICR4 = 1000;
        OCR4A = 800;

        for(;;);
}

This works on the real hardware work but does not work on the simulator (port is never set).

Thank you very much

simavr does not simulate the pin changes due to fast PWM; i.e, no bitbanging.
