Quantity of variation judged as on for each channel can be set with an unsigned 16-bit integer.
Users can alter this setting (in setup mode) or rewrite it by teaching. It cannot be changed by drift

Sets the ratio of the quantity of variation judged as on (THRx) to the measured value observed in
Only the lower-order 4 bits are valid. If the other bits are written to, they are ignored.
If the measured value changes by ∆A due to a touch during teaching, the quantity of variation judged
Quantity of variation judged as on (THRx)
For example, if RTHRx = 10, the quantity of variation judged as on (THRx) is:
Used in teaching.
Sets the ratio of hysteresis (HYSx) to the measured value observed in teaching with an unsigned 4-bit
Only the lower-order 4 bits are valid. If the other bits are written to, they are ignored.
