The IGATE level and the TCC level reported in Table 9 and in Table 10 refer to an analog voltage that is a fraction

of VDD. Therefore, the selected level on the pins can be configured by two resistor dividers, one for IGATE and

one for TCC.

Table 11 summarizes the VDD ratio for each level and a suggested pair of standard resistor values suitable for

each configuration, the R1 and R2 resistors are defined as shown in Figure 13.
