Oscillator Control
W78E58B/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 above 24 MHz. The value of R and C1, C2 may
need some adjustment while running at lower gain.
