The input buffer is shown in Figure 59. This input buffer is connected to the intermediate nodes between the 1st stage switch and the 2nd stage switch for each port output (C_SBU1/2, C_USB_TP/N, C_USB_BN/P). The input buffer is enabled via firmware when monitoring digital signals and disabled when an analog signal is desired. See theFigure 45 section for more detail on the pullup and pulldown resistors of the intermediate node.
