13.1 Quartz frequency adjustment
13.1.1
Method 1: fixed OSCI capacitor
By evaluating the average capacitance necessary for the application layout, a fixed
capacitor can be used. The frequency is best measured via the 32.768 kHz signal
available after power-on at pin CLKOUT. The frequency tolerance depends on the
quartz crystal tolerance, the capacitor tolerance and the device-to-device tolerance
(on average
±
5
×
10
6
). Average deviations of
±
5 minutes per year can be easily
achieved.
13.1.2
Method 2: OSCI trimmer
Using the 32.768 kHz signal available after power-on at pin CLKOUT, fast setting of a
trimmer is possible.
13.1.3
Method 3: OSCO output
Direct measurement of OSCO out (accounting for test probe capacitance).
