5.4
5.4.1
Setting the IDL bit in the PCON register enters the idle mode. In the idle mode, the internal clock to
the processor is stopped. The peripherals and the interrupt logic continue to be clocked. The
processor will exit idle mode when either an interrupt or a reset occurs.
5.4.2
When the PD bit in the PCON register is set, the processor enters the power-down mode. In this
mode all of the clocks are stopped, including the oscillator. To exit from power-down mode is by a
hardware reset or external interrupts INT0 to INT1 when enabled and set to level triggered.
5.4.3
The W78L365A allows user to diminish the gain of on-chip oscillator amplifier by using programmer to
clear the B7 bit 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 affect the
external crystal operating improperly at high frequency. The value of C1 and C2 may need some
adjustment while running at lower gain.
