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, Pro-Touch2, for configuring the USB5806 functions,

registers and OTP memory. All configuration is to be performed via the Pro-Touch2 programming tool. For additional

information on the Pro-Touch2 programming tool, refer to Software Libraries within Microchip USB5806 product page

at www.microchip.com/USB5806.

6.1

Customer Accessible Functions

The following functions are available to the customer via the Pro-Touch2 Programming Tool.

6.1.1

USB ACCESSIBLE FUNCTIONS

6.1.1.1

I2C Bridging Access over USB

Access to I2C devices is performed as a pass-through operation from the USB Host. The device firmware has no knowl-

edge of the operation of the attached I2C device. For more information, refer to the Microchip USB5806 product page

and Pro-Touch2 at www.microchip.com/USB5806.

6.1.1.2

SPI Access over USB

Access to an attached SPI device is performed as a pass-through operation from the USB Host. The device firmware

has no knowledge of the operation of the attached SPI device. For more information, refer to the Microchip USB5806

product page and SDK at www.microchip.com/USB5806.

6.1.1.3

OTP Access

The OTP ROM in the device is accessible via the USB bus during normal runtime operation or SMBus during the

SOC_CFG stage. For more information, refer to the Microchip USB5806product page or the Pro-Touch2 User’s Guide.

6.1.1.4

Battery Charging Access over USB

The Battery charging behavior of the device can be dynamically changed by the USB Host when something other than

the preprogrammed or OTP programmed behavior is desired. For more information, refer to the Microchip

USB5806product page or the Pro-Touch2 User’s Guide.

6.1.2

SMBUS ACCESSIBLE FUNCTIONS

OTP access and configuration of specific device functions are possible via the USB5806 SMBus slave interface. All OTP

parameters can be modified via the SMBus Host. For more information refer to the Microchip USB5806 product page.

Note:

Device configuration straps and programmable pins are detailed in Section 3.5, Configuration Straps and

Programmable Functions.

Refer to Section 7.0, Device Interfaces for detailed information on each device interface.

Note:

For additional programming details, refer to the Pro-Touch2 programming tool User’s Guide.

Note:

Refer to Section 7.3, I2C Bridge Interface for additional information on the I2C interface.

Note:

Refer to Section 7.1, SPI Master Interface for additional information on the SPI.
