Preliminary W78LE516
Oscillator Control
W78LE516/E516 allow user to diminish the gain of on-chip oscillator amplifier by using programmer
to set the bit B7 of security register. Once B7 is set to 0, a half of gain will be decreased. Care must
be taken if user attempts to diminish the gain of oscillator amplifier, reducing a half of gain may
improperly affect the external crystal operation at high frequency. The value of C1 and C2 may need
some adjustment while running at lower gain.
