tained in firmware. Trip Firmware Value is provided by the evaluation board's firm-
ware, using an algorithm that calculates the optimum trip values based on the
average value. These values are sent to the mTouch Diagnose Tool through the
USB/I2C/UART connection, and are constantly updated and displayed on the bar
graphs; this is enabled by default. When selecting GUI Values, the trip levels are
calibrated from host and sent to the embedded firmware by USB/I2C/UART which
takes them into account for internal calculations.
