5.2 DAC pin limitations

The DAC output of the PIC16F18446 is on a shared pin with the ICSP clock signal. Due to the load introduced by the presence of pull-down resistor R204, required for debugging, the DAC output will not be as linear as the ideal output.

If a more linear response is desired, R204 can be removed. Be warned that this modification will render debugging unusable. Kit programming is not affected by this limitation and can be done regardless of whether R204 is mounted.
