As the low-speed RC oscillation circuit has temperature variation, the software performs the frequency adjustment
according to the temperature by using the frequency adjustment function in the low-speed RC oscillation circuit. The
software calculates a trimming value using following three parameters and primary approximate equation in the area of
low temperature - ordinary temperature and ordinary temperature - high temperature, and then sets it to the low-speed
RC oscillation frequency adjustment register.
[parameter]
1.Temperature sensor A/D conversion value of the current temperature, for the low-speed RC oscillation frequency
Adjustment
2.Temperature sensor A/D conversion value of the ordinary temperature (25 oC), for the low-speed RC oscillation
frequency
Adjustment
3.Coefficient

Ÿ
Use the RC oscillation adjustment sample software provided by LAPIS. Otherwise, the operation is not
guaranteed.
