13.1.1 Method 1: fixed OSCI capacitor
13.1.2 Method 2: OSCI trimmer
13.1.3 Method 3: OSCO output
13.1 Quartz frequency adjustment
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
achieved.
Using the 32.768 kHz signal available after power-on at pin CLKOUT, fast setting of a
trimmer is possible.
Direct measurement of OSCO out (accounting for test probe capacitance).
