2.2.5 Using the USB Interface Connection

The on-board MSP430F5529 USB microcontroller (U6) provides an I2C host interface to the LMK3H2108 peripheral device. The device registers can be controlled with the USB using the TICS Pro 2 software running on a host PC. J20 can be used with an external USB2ANY as an alternative to using the on-board USB2ANY.

If the USB2ANY firmware needs to be updated, the S1 button serves as the BSL connection. Press the S1 button to mimic pressing the BSL button of an external USB2ANY. Release the button after updating the firmware.
