15
XOUT
16
XIN
Crystal oscillator
pin
These pins are used for a crystal
oscillator.
A 75-kHz reference crystal oscillator is
connected to the pins XIN and XOUT.
17
PLL GND
Power supply
input pin
This is a power supply input pin for the
PLL block.
18
OUT1
(ST)
General-purpose
output port
(ST port)
This port can be switched between
general-purpose output port and ST
output using STC bit of serial data.
Note: Upon power-on or power-on reset,
pin 18 is configured as an output
(the OUT1 output will be low).
Thus, If an LED is connected to pin
18 for stereo display, it is
illuminated at these times.
19
OUT2
(DO2)
General-purpose
output port
(DO output)
This port can be switched between
general-purpose output port and DO
output using DO2 bit of serial data.
20
DO
Phase
comparator
output
This is a phase comparator output pin for
the PLL block with tri-state output.
When the divided-down clock from the
programmable counter is higher than the
reference frequency, it will be in
High-level. When it is lower, it will be in
Low-level. If it matches the reference
frequency, it will be in high-impedance
state.
The output is held at Low in Standby
Mode.
21
PLL VCC
Power supply
input pin
This is a power supply input pin for the
PLL block.
