Tuning of the thresholds

25

If one of these thresholds must be greater than 255, the TSLPRM_COEFF_TH must be set

in order to bring the value in the correct range [0;255]. This is obtained by dividing all

thresholds, except the calibration threshold, by 2 to the power of TSLPRM_COEFF_TH. In

that case, the divided coefficients values (except for the calibration threshold) are the values

that need to be configured in the firmware. A compensation factor of 2 to the power of

TSLPRM_COEFF_TH will then be applied to all coefficients (except the calibration

threshold) by the firmware.
