Howdy,
on the PIC32MX120F errata I can read:

---

Module: ADC
If the ADC module is configured to operate at a maximum conversion rate of =
1.1 Msps, missing codes are possible every 32 codes and the DNL parameter w=
ill not be within the published specification.

Work around:
Configure the ADC module to operate for a maximum conversion rate of 500 ks=
ps.

---

I don't understand what it exactly means: what are "missing codes"?

If I simply lose the least significant bit precision (DNL?) then it's worth=
 to keep it at 1.1Msps, as speed is prioritary for me and I need only the t=
opmost 6-7 bits of precision anyway.

Of course if I get meaningless results, I will step down to 500Msps.

Cheers,
MarI/O
