Hi, I am using Arduino Nano and I found I cannot access high byte of any Timer 1 registers. For example
cli(); OCR1A=0xffff; Serial.println(OCR1A,DEC); OCR1B=0xffff; Serial.println(OCR1B,DEC); sei();
Also using direct access to OCR1AH and OCR1AL (in the right order) returns 0 every time as content of OCR1AH. The same is true for OCR1BH/L, TCNT1 etc. It looks as if only lower byte is implemented. Is it possible???
