Not all specifications are 100 percent tested. All Min/Max limits are guaranteed by Nuvoton via design,

electrical testing and/or characterization.

When different F_Sis applied, the value will change accordingly. Also, stability of internal oscillator may

vary as much as +10% over the operating temperature and voltage ranges.

k = 1000.
