I want to enable it for value number o to 99

if (pin < A0) {
pin += A0;
}

pinPeripheral(pin, PIO_ANALOG);

if (pin == A0) { // Disable DAC, if analogWrite(A0,dval) used previously the DAC is enabled
syncDAC();
DAC->CTRLA.bit.ENABLE = 0x00; // Disable DAC
//DAC->CTRLB.bit.EOEN = 0x00; // The DAC output is turned off.
syncDAC();
}

Start by locating the source file containing the pinPeripheral(pin, PIO_ANALOG) and DAC disable snippet, then determine what “value number o to 99” is intended to enable. Check whether the repository has tests or examples covering this behavior; completion criteria are not specified in the issue and need clarification.
