18
Local
• FMIN is selected when DVS in the serial data
oscillator
input is set to 1.
signal input _{• The input frequency range is from 10 to}
160 MHz.
• The signal is transmitted to the swallow
counter.
• The divisor can be set to a value in the range
272 to 65535.
27
Chip enable • This pin is set high during serial data input to
the PLL (DI) or during serial data output (DO).
29
Clock
• This pin is the clock for data synchronization
during serial data input to the PLL (DI) or
during serial data output (DO).
28
Input data _{• This is the input pin for serial data that is}
transferred from the controller to the PLL.
30
Output data _{• This is the output pin for serial data that is}
transferred from the controller to the PLL.
VDD
19
Power supply _{• This is the PLL power supply pin. Supply 4.5 V}
to 5.5 V to this pin when the PLL is operating.
• When power is first applied to this pin, the
power-on reset circuit operates.
VSS
21
Ground • This is the PLL ground pin.
I/O-1

General-
purpose
I/O ports
• These are general-purpose I/O ports.
• The output circuits open-drain.
• During a power-on reset, I/O-1 and I/O-2
become input ports. STSD SW becomes an
output port, and is fixed low.
• These ports can be switched between input
and output according to the serial data that is
transferred from the controller (I/O-1, I/O-2,
STSD SW).
SEEK SW
33
General-
purpose
I/O port
• This is a general-purpose I/O port.
• The output circuits are complementary
circuits.
• During a power-on reset, this port becomes
an input port.
• This port can be specified as an input or
output port by the serial data that is trans-
ferred from the controller.
ADC0
34
ADC input
• This is the A/D converter input pin.
The converter is a 6-bit successive-approxi-
mation A/D converter.
For details, refer to the page that describes
the A/D converter configuration.
