R/W
HSICLK14 Trim
The product has been calibrated to 14MHz±1% when leaving the factory.
However, it changes as the temperature and voltage changes, but the
frequency of HSICLK14 RC oscillator can be adjusted by HSI14TRM.

HSICLK14 Calibrate
It will be calibrated to 14MHz±1% before leaving the factory. When the
system is started up, the calibration parameters will be automatically
written to the register.
