The association timer2 <-> pin3 and timer1 <-> pin9 is hard coded in the chip design. ArminJo is right. The ATmega328p is an old and simple chip. If you want more flexibility, select another chip/board. (Have you have a look at the Duo? It is a beast in this regard.) |

You can use pin 11 with timer 2 but you cannot generate 30% PWM at 38 kHz with pin 11. |

So there is no way to generate a signal with the same quality and accuracy as pin 3 on other pins. |
