As you might know the 80c537 is capable to select the internal voltage reference by writing into DAPR where the higher nibble selects VintREF and the lower VintGND I tried this with the eval version of A51 7.03 and its just converting in the standard range(Vintgnd=0v, Vintref=5V) I used an external SFR definition library but since the conversion gets started this shouldn't be the problem. Someone knows a solution/ got the same problem? thx in advance
