W78LE516/W78L516A
- 8 -
5.3 Clock
The W78L516 is designed with either a crystal oscillator or an external clock. Internally, the clock is
divided by two before it is used by default. This makes the W78L516 relatively insensitive to duty
cycle variations in the clock.
5.4 Crystal Oscillator
The W78L516 incorporates a built-in crystal oscillator. To make the oscillator work, a crystal must be
connected across pins XTAL1 and XTAL2. In addition, a load capacitor must be connected from each
pin to ground.
5.5 External Clock
An external clock should be connected to pin XTAL1. Pin XTAL2 should be left unconnected. The
XTAL1 input is a CMOS-type input, as required by the crystal oscillator.
5.6 Power Management
Idle Mode
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.
Power-down Mode
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.
5.7 Reduce EMI Emission
The W78L516 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.
