DEVICE CONFIGURATION

The device supports a large number of features (some mutually exclusive), and must be configured in order to correctly

function when attached to a USB host controller. The hub can be configured either internally or externally depending on

the implemented interface.

Microchip provides a comprehensive software programming tool, MPLAB Connect (formerly ProTouch2), for OTP con-

figuration of various USB4715 functions and registers. All configuration is to be performed via the MPLAB Connect Con-

figurator programming tool. For additional information on this tool, refer to th MPLAB Connect Configurator

programming tool product page at http://www.microchip.com/design-centers/usb/mplab-connect-configurator.

Additional information on configuring the USB4715 via SMBus is provided in the AN2439 - Configuration of the

USB491x/USB492x/USB4715” application note, which contains details on the hub operational mode, SOC configuration

stage, OTP configuration, USB configuration, and configuration register definitions. This application note, along with

other USB4715 resources, can be found on the Microchip USB4715 product page at www.microchip.com/USB4715.

Device configuration straps and programmable pins are detailed in Section 3.3, "Configuration Straps and
