W78LE58/W78L058A
Oscillator Control
W78L058A/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 20 MHz. The value of R and
C1, C2 may need some adjustment while running at lower gain.
