Two threshold levels (upper and lower) can be set for IR Sensor output in these registers.
IR Upper Threshold level
THIRH[7:0]: Lower 8-bit of IR Upper Threshold level
THIRH[15:8]: Upper 8-bit of IR Upper Threshold level
IR Lower Threshold level
THIRL[7:0]: Lower 8-bit of IR Lower Threshold level
THIRL[15:8]: Upper 8-bit of IR Lower Threshold level
Threshold code should be set as the target value of measurement data, and set as THIRH ≥ THIRL.

Two threshold levels (upper and lower) can be set for Temperature Sensor output in these registers.
Temperature Sensor Upper Threshold level
THTMPH[7:0]: Lower 8-bit of Temperature Sensor Upper Threshold level
THTMPH[15:8]: Upper 8-bit of Temperature Sensor Upper Threshold level
Temperature Sensor Lower Threshold level
THTMPL[7:0]: Lower 8-bit of Temperature Sensor Lower Threshold level
THTMPL[15:8]: Upper 8-bit of Temperature Sensor Lower Threshold level
Threshold code should be set as the target threshold value of measurement data, and set as THTMPH ≥
THTMPL.
