7.5.1.3
Note 1: this is the frequency tolerance when all trimming codes are 0.
Note 2: frequency shift as a function of VBAT with normal regulator function.
Note 3: frequency shift as a function of VBAT while the regulator is short-circuited to VBAT.
The tolerances on the minimal frequency and the drift with supply or temperature can be cancelled using the
software DFLL (digital frequency locked loop) which uses the crystal oscillator as a reference frequency.
