значит, вот как я инициализирую

char __low_level_init (void) {





PORTB = (0<<7)|(0<<6)|(0<<5)|(0<<4)|(0<<3)|(0<<2)|(0<<1)|(0<<0);
DDRB =(1<<7)|(1<<6)|(1<<5)|(1<<4)|(1<<3)|(1<<2)|(1<<1)|(1<<0);

PORTD = (0<<7)|(0<<6)|(0<<5)|(0<<4)|(0<<3)|(0<<2)|(0<<1)|(0<<0);
DDRD =(1<<7)|(1<<6)|(0<<5)|(1<<4)|(1<<3)|(1<<2)|(1<<1)|(1<<0);

__watchdog_reset();
WDTCR= (1 << WDCE) | (1 << WDE);
WDTCR= (1 << WDP2) | (1 << WDP1) | (1 << WDP0);


return 1;
}
