The USB2524 has three configuration pins CFG_SEL[2:0], that determines the operating mode of the USB2524. The
selection of a configuration is done with six resistor combinations shown in Table 3.1. Only three resistors are
installed to either pull up or pull down each configuration pin. Figure 3.1 shows a section of the PCB for the EVB-
USB2524 where the resistors are located.
