impedance, only shifted by the Reference Delay Parameter, which is usually constant during
the application runtime and set only during initial tuning. Therefore, it can be used to monitor
the raw sensor data of every channel individually for advanced sensing applications. The
Impedance and Reference Impedance register values are updated once per AIC interval.
For Slider and similar applications, the (positive) difference between Impedance and
Reference Impedance can be used as strength value for each channel, and using an
interpolation algorithm, high-resolution poison information can be calculated. Please refer to
the SK-TSC-1127-SB example software for implementation details (available on the Fujitsu
Web site mentioned in the appendix of this document).
