with f
from the value predicted by the equation.
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.
