The VRCON register (Register 7-3) controls the voltage reference module shown in Figure 7-8. 7.6.1 CONFIGURING THE VOLTAGE REFERENCE The voltage reference can output 32 distinct voltage levels, 16 in a high range and 16 in a low range. The following equation determines the output voltages: EQUATION 7-1: 7.6.2 VOLTAGE REFERENCE ACCURACY/ERROR The voltage reference is VDD derived and therefore, the CVREF output changes with fluctuations in VDD. The tested absolute accuracy of the comparator voltage reference can be found in Section 15.0 “Electrical Specifications”. FIGURE 7-8: COMPARATOR VOLTAGE REFERENCE BLOCK DIAGRAM VRR = 1 (low range): CVREF = (VR<3:0>/24) x VDD VRR = 0 (high range): CVREF = (VDD/4) + (VR<3:0> x VDD/32) VRR 8R VR<3:0> 16-1 Analog 8R RR RR CVREF to 16 Stages Comparator Input VREN VDD MUX |
