    1. The TSI module is functional with capacitance values outside this range. However, optimal performance is not guaranteed.
    2. The programmable current source value is generated by multiplying the SCANC[REFCHRG] value and the base current.
    3. Measured with a 5 pF electrode, reference oscillator frequency of 10 MHz, PS = 128, NSCN = 8; Iext = 16.
    4. Measured with a 20 pF electrode, reference oscillator frequency of 10 MHz, PS = 128, NSCN = 2; Iext = 16.
    5. Measured with a 20 pF electrode, reference oscillator frequency of 10 MHz, PS = 16, NSCN = 3; Iext = 16.
    6. Measured with a 20 pF electrode, reference oscillator frequency of ~5 MHz (IREF = 5 μA, REFCHRG = 4), PS = 128,
    NSCN = 2; Iext = 16 (EXTCHRG = 15).
    7. Typical value depends on the configuration used.
    8. Time to do one complete measurement of the electrode. Sensitivity resolution of 0.0133 pF, PS = 0, NSCN = 0, 1
    electrode, DELVOL = 2, EXTCHRG = 15.
