1. The TSI module is functional with capacitance values outside of 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. The programmable current source value is generated by multiplying the SCANC[EXTCHRG] value and the base current
4. Measured with a 5pF electrode, reference oscillator frequency of 10MHz, PS = 128, NCSC = 8; Iext = 16
5. Measured with a 20pF electrode, reference oscillator frequency of 10MHz, PS = 128, NCSC = 2; Iext = 16
6. Measured with a 20pF electrode, reference oscillator frequency of 10MHz, PS = 16, NCSC = 3; Iext = 16
7. 6.2ms scan time
8. 1pF electrode capacitance with 4.96ms scan time
9. Time that takes to do one complete measurement of the electrode. Sensitivity resolution of 0.0133pF
