Encryption
This bit is used to enable/disable the encryption logic for code protection. Once encryption feature is
enabled, the data presented on port 0 will be encoded via encryption logic. Only whole chip erase will
reset this bit.
Oscillator Control
W78E365 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.
