after work is completed.
CD PICK-UP MAINTENANCE
About pick-up (Optical lens) Cleaning
Clean a lens with swab of the cotton which moistened it with alcohol, cleaning paper or cleaning disc appointed.
Specified cleaning disc : LC-1 (Part code : 645 026 1961 ..... manufactured by SANYO.)
Show a clean procedure in the following in reference by swab of cotton.
1. Cotton swab is wrapped with Cleaning paper.
2. Add the isopropyl alcohol.
3. Gently move the tip of cotton swab just like a draw a whirlpool from inside to outside on the surface of lens.

Universal counter / general-purpose input port.
The IOS instruction b3 with Pn=3 switches the pin function
between universal counter input and general-purpose input.
• Frequency measurement
The universal counter function is selected by an IOS
instruction with Pn=3 and b2=0. HCTR frequency measure-
ment mode is set up by a UCS instruction with b3=0 and b2=0,
and counting is started with a UCC instruction after the count
time is selected. The CNTEND flag is set when the count
completes. To operate this circuit as an AC amplifier in this
mode, the input must be capacitor coupled.
• For use as the general-purpose input pin.
The general-porpose input port function is selected by an IOS
instruction with Pn=3 and b2=1. An internal register (address
OEH) input instruction INR(b0) is used to acquire data from
this pin.
Input is disabled in clock stop mede (the input pin will be pulled
down.) During the power-on reset, the universal counter function
is selected.
SNS
Voltage sense / general-purpose input pin port.
This circuit is designed for a relatively low input threshold voltage.
• For use as the voltage sense pin
This input pin is is used to determine whether or not a power
failure occurred after recovery from backup (clock stop) mode.
An internal sense F/F is used for this determination. The
sense F/F is tested with a TUL instruction (b2).
• For use as the general-purpose input port
When used as a genaral-purpose input port, the state is
sensed by using a TUL instruction (b3).
Since unlike other input ports, input is not disablle in clock
stop mode and during the power-on reset, special care is
required with respect to through currents.

Universal counter (freqency and period measurement) / general-

This IOS instruction b3 with Pn=3 swithes the pin function
between universal counter input and general-puropse input.
• Frequency measurement
The universal counter function is selected by an IOS
instruction with Pn=3 and b3=0. LCTR frequency measure-
ment mode is set up by a UCS instruction with b3=0 and b2=1,
and counting is started with a UCC instruction after the count
time is selected. The CNTEND flag is set when the count
completes. To operate this circuit as an AC amplifier in this
mode, the input must be capacitor coupled.
• Period measurement
With the universal counter function selected, a UCS instruction
with b3=1 and b2=0 sets up the period measurement mode
and a UCC instruction starts counting after selecting the
count time. The CNTEND flag is set when the count
completes. In this mode, the signal must be input with DC
coupling to turn off the bias feedback resistor.
• For use as general-purpose input pin use.
The general-purpose input port function is selected by an IOS
instruction with Pn=3 and b3=1. An internal register (address
OEH) input instruction INR(b1) is used to acquire data from
this pin. Input is disabled in clock stop mode. (The input pin
will be pulled down.) During the power-on reset. The universal
counter function(in HCTR frequency measurement mode) is
selected.
HOLD
PLLcontrol and CLOCK STOP mode control pin.
Setting this pin low in the hold enable state disables input to the
FMIN and AMIN pins and sets the E0 pin to the high-impedance
state. To enter clocl stop mode, set the HOLDEN flag, set this pin
low, and execute a CKSTP instruction. To clear clock stop mode
set this pin high.
General-purpose input ports/ADC input pins.
The IOS instruction with Pn=7 switches the pin function between
genetal-purpose input ports and ADC inputs.
• For use as the general-purpose input port
The IOS instruction with Pn=7 specifies the use as general-
purpose input port in bit units.
• For use as ADC input pin
The IOS instruction with Pn=7 specifies the use as ADC in bit
units. The IOS instruction with Pn=1 specifies the pin to
convert. The UCC instruction (b2) starts a conversion.
The ADCE flag will be set when the conversion completes.
Note) Executing an input instruction for a port specified for ADI
use will always return low since input is disabled. These
pins must be set up for general-purpose input port usage
before an input instruction is excuted. (In other words, the
port must be set to the general-porpose input function
before the input instruction is executed.)
Input is disabled in clock stop mode. During the power-on reset
these pins go to the general-purpose input port function.

General-purpose output ports/DAC input pin.
The IOS instruction with Pn=9 switches the pin function between
general-purpose output ports and ADC inputs. Since these pins
are open drain circuit, pull-up resistors are required in exrernal
circuit accepting these outputs.
• For use as general-purpose output port
The IOS instruction with Pn=9F specifies general-purrpose
input port use in bit units.
• For use as DAC
The IOS instruction Pn=9 is used to switch the port in bit units.
DAC data is loaded into tne DAC (0 to 3) specified with the
DAC instruction, Although PWM waveform is output as soon
as the port is switched, the data prior to that load is output for
up to 114µs (1/8.791kHz) after data is loaded.
The general-purpose output port function is selected after a power
-on reset, and the output go to the transistor off (H output) state.
General-purpose I/O / external interrupt ports
There is no instruction that switches the function between general-
purpose ports and external interrupt ports. These pins function for
input only when the external interrupt enable flag is set.
(Output disables)
• For use as general-purpose I/O port
These pins can be set for input or output in bit units (bit I/O).
The IOS instruction is used to specify input or output in bit
units.
• For use as external interrupt pin
This function can be used by setting the external interrupt
enable flags (INT0EN and INT1EN) in status register 2.
The corresponding pin is automatically set to the input port.
To enable interrupt operation, the interrupt enable flag (INTEN)
in status register 1 must also be set. The IOS instruction with
Pn=3, b1=INT1, and b0=INT0 is used to select rising or falling
edge detection.
In clock stop mode, input is disabled and these pins go to the high-
impedance state. During the power-on reset, these pins go to the
general-purpose input port function.
