CLKFX period change in free
running oscillator mode at the
same temperature.
FCLKFX > 50 MHz
CLKFX period change in free
running oscillator mode at the
same temperature.
FCLKFX < 50 MHz
CLKFX period will change in
free_oscillator mode over
temperature. Add to
CLKFX_FREEZE_VAR to
determine total CLKFX period
change. Percentage change for
CLKFX period over 1°C.
