59 / 88 page 000-0046127-101 Page 58 of 87 SLG46127 15.0 Voltage Reference (VREF) 15.1 Voltage Reference Overview The SLG46127 has a Voltage Reference Macrocell to provide references to the two analog comparators. This macrocell can supply a user selection of fixed voltage references, /3 and /4 reference off of the VDD power supply to the device, and externally supplied voltage references from PIN1. The macrocell also has the option to output reference voltages on PIN10. See table below for the available selections for each analog comparator. Also see Figure 40 below, which shows the reference output structure. 15.2 VREF Selection Table Table 42. VREF Selection Table. SEL<4:0> ACMP0_VREF ACMP1_VREF 11010 ext. Vref (PIN1) ext.
