AUTO500
This switch specifies the function of the MAN UP and MAN DWN keys. With the AUTO500 switch, it is
possible to use the MAN UP and MAN DWN keys also for auto-tuning (seek operation), as follows.
AUTO500
MAN UP and MAN DWN key function

Only manual tuning is performed.
Each time the key is pressed, the frequency counter is incremented or decremented by
one channel. Keeping the key pressed for at least 0.5 seconds triggers manual fast
increment/decrement.
1
Both manual and auto-tuning are performed.
Each time the key is pressed, the frequency counter is incremented or decremented by

AUTOLOC
Description
This switch specifies the local function, as follows:
AUTOLOC
Local function
0
Either or DX mode is selected according to a key entry (no auto local function available).
Each time the MONO/LOC key is pressed, switching occurs between local and DX
modes.
The local output is high in the local mode during auto-tuning (seek, scan, or auto-store).
1
The auto local function is performed (if available).
The MONO/LOC key becomes ineffective.
Keeping the SEEK UP , SCAN UP , SCAN DWN or P.SCAN key for at least 2
seconds triggers auto-tuning, turns on the “LOC” display, and makes the local output
high. After one cycle of auto-tuning is completed, a search begins in DX mode (with the
“LOC” display off and local output at a low level).
In modes other than auto-tuning , the “LOC” display is off and the local output is low. If
a key for the same operation (for example, the SEEK UP key during seek operation) is
pressed in local mode during auto-tuning, a search begins in DX mode at the same
frequency used when auto-tuning began. If the key is pressed in DX mode, auto-tuning
stops, and the frequency that was selected when auto-tuning began is reselected.
The same operation as above occurs when the AUTO500 is set to 1 (by keeping the
MAN UP or MAN DWN key pressed for at least 0.5 seconds).

POWER
The POWER key is used to control the power-on/off of the radio in momentary key mode. It is effective
when the IGNITION pin is at a high level. Pressing this key inverts the output of the POWER pin.
When the POWER pin output is set to low (the power is turned off), the tape recorder, CD player and radio
are forced to be turned off even when they have been in the power-on state. In this case, they are turned
off with or without clock display, according to whether they were in clock mode or non-clock mode.
The power-on mode varies as follows according to the state of the RDSET, TPSET, and CDSET switches.

This key functions as a preset scan and auto-storage key. The operation triggered by the key varies
depending on the state of the DISAMEMO initial setting diode.
(1) When DISAMEMO = 0 (with the auto-storage function):
The operation varies depending on the timing at which the key is operated.
(a) If the key is released within 2 seconds:
The preset scan operation begins immediately when the key is released.
(b) If the key is pressed for at least 2 seconds:
The auto-storage operation begins when 2 seconds elapse.
(2) When DISAMEMO = 1 (without the auto-storage function):
The preset scan operation begins immediately when the key is pressed.
The preset scan and auto-storage functions are described below.
Preset scan operation
The contents of each preset memory are called for 5 seconds each time automatically.
If a frequency other than those in the preset memories is being received, calling begins at M1. If
a frequency recorded in a preset memory is being received, calling begins at the preset memory
numbered one higher than that preset memory (for example, at the M4 preset memory if a
frequency recorded in the M3 preset memory is being received). This operation is illustrated
below.

display does not blink.
To stop preset memory scanning during a 5-second hold period, press the P. SCAN key again or a preset
memory key that corresponds to the preset memory being currently accessed. It is possible to write to a
preset memory when another preset memory is on hold (for example, write to the M5 when the M1 is on
hold). When a write operation is completed, the preset scan operation ends.
Hold down one of the M1 to M6 keys for at least 2 seconds during the preset scan operation. The
frequency currently being received is written into the preset memory corresponding to the pressed key.
The preset scan operation ends immediately when any of these keys is pressed.

P.SCAN
Description
Auto-storage function
Broadcasting stations are searched for automatically. The frequency of a detected station is written
to a preset memory. A method used to detect a station is determined according to the states of the
ENAMIF and ENFMIF initial setting diodes. A broadcasting station search begins at the frequency
being currently received and is performed through the frequencies in the ascending order.
When a station is detected, its frequency is written to a preset memory.
For the voltage with SD, see the description of the SD in Chapter 1.
The auto-storage operation varies depending on the state of the AUTOLOC initial setting diode as
follows:
(1) When AUTOLOC = 0 (with no auto local function):
The auto-storage function varies depending on which mode has been selected, local or DX, when the
function begins.
(a) If DX mode has been selected when the auto-storage function starts:
A search beings at the frequency being currently received and continues in the ascending order of
the frequency. When all frequencies are searched through, the search operation ends. If the
P. SCAN key is pressed during the search operation, the auto-storage operation ends, and the
frequency selected when the auto-storage operation began is received.
When all frequencies are searched through, if at least one station is detected, the contents of the
preset memories are updated, and the preset scan begins at the M1 preset memory.
How the contents of the preset memories are updated varies depending on the number of stations
detected.
If six or more stations are detected:
If six or more stations are detected, six stations with a higher SD input are selected and
written to the preset memories. A lower frequency is written to a lower-numbered preset
memory.
If less than six stations are detected:
If less than six stations are detected, lower frequencies are written to lower-numbered preset
memories. The contents of a preset memory will not be changed if there is no frequency
corresponding to it.
(b) If local mode has been selected when the auto-storage function starts:
A search begins in local mode at the frequency being currently received and continues in the
ascending order of the frequency. When all frequencies are searched through, if six or more
stations are not detected, the search switches to DX mode and continues in it. If six or more
stations are detected in local mode, or all frequencies are searched through in DX mode, the
auto-storage operation ends.
Pressing the P. SCAN key during the search operation stops the auto-storage operation, and
causes the frequency selected when the auto-storage memory began to be received.
If six or more stations are detected in local mode, or all frequencies are searched through in DX
mode, the auto-storage operation ends. If at least one station is detected, the contents of the
preset memories are updated, and the preset scan begins with the M1 preset memory.
How the contents of the preset memories are updated varies depending on the number of stations
detected, as follows:
If six or more stations are detected in local mode:
If six or more stations are detected, six stations with a higher SD input are selected and
written to the preset memories. A lower frequency is written to a lower-numbered preset
memory
If less than six stations are detected in local mode and some are detected in DX mode,
resulting in a total of six or more stations being detected:
Stations detected in DX mode with higher SD input levels are selected and added to the
number of stations detected in local mode so that the total becomes six. In this case, the
stations detected in local mode are excluded from those detected in DX mode.
The frequencies of the six stations are written to the preset memories, with a lower frequency
written to a lower-numbered preset memory.

µPD17012GF-058
Momentary key
P.SCAN
Description
If less than six stations are detected in local mode and some are detected in DX mode,
resulting in a total of less than six stations being detected:
If the same station is detected in DX and local modes, the station detected in DX mode is
deleted so that the same frequency will not be written to two preset memories. The frequencies of the less than six stations detected are written to the preset memories, with a lower
frequency written to a lower-numbered preset memory. The contents of a preset memory will
not be changed if there is no frequency corresponding to it.
(2) When AUTOLOC = 1 (with the local function):
A search begins in local mode at the frequency being currently received and continues in the ascending order of the frequency. When all frequencies are searched through, if six or more stations are not
detected, the search switches to DX mode and continues in it. If six or more stations are detected in
local mode, or all frequencies are searched through in DX mode, the auto-storage operations ends.
Pressing the P. SCAN key in local mode switches to DX mode, and restarts the search operation at
the frequency selected when the previous search began. Any stations detected in local mode are
made ineffective. (Stations detected in local mode are excluded during preset memory updating.)
Pressing the P. SCAN key in DX mode ends the auto-storage operation, and causes the frequency
selected when the auto-storage operation began to be received.
If six or more stations are detected in local mode, or all frequencies are searched through in DX mode,
the auto-storage operation ends. If at least one station is detected, the contents of the preset memories are updated, and the preset scan begins with the M1 preset memory.
How the contents of the preset memories are updated varies depending on the number of stations
detected, as follows:
If six or more stations are detected in local mode:
If six or more stations are detected in local mode, six stations with a higher SD input are selected
and written to the preset memories, with a lower frequency written to a lower-numbered preset
memory.
If less than six stations are detected in local mode, and some are detected in DX mode,
resulting in a total of six or more stations being detected:
Stations detected in DX mode with higher SD input levels are selected and added to the number of
stations detected in local mode so that the total becomes six. In this case, the stations detected in
local mode are excluded from those detected in DX mode.
The frequencies of the six stations are written to the preset memories, with a lower frequency
written to a lower-numbered preset memory.
If less than six stations are detected in local mode and some are detected in DX mode,
resulting in a total of less than six stations being detected:
If the same station is detected in DX and local modes, the station detected in DX mode is deleted
so that the same frequency will not be written to two preset memories. The frequencies of the less
than six stations detected are written to the preset memories, with a lower frequency written to a
lower-numbered preset memory. The contents of a preset memory will not be changed if there is
no frequency corresponding to it.

SCAN UP
SCAN DWN
The SCAN UP and SCAN DWN keys are used for auto-tuning (scan operation).
Pressing the SCAN UP key ( SCAN DWN key) increases (decreases) the frequency by one channel
space and checks whether there is a broadcasting station at each reception frequency (frequency counter
and SD signal). If a broadcasting station is detected, the corresponding frequency is held for five seconds.
If no key is pressed within this hold time of five seconds, the seek operation restarts. If another broadcasting station is detected, the corresponding frequency is held in the frequency counter for five seconds. This
operation is repeated (scan operation) sequentially.
The frequency display blinks at 1 Hz (with a duty cycle of 50%) during the five-second hold time. A beep
occurs at the end of the hold time.
The seek operation here is the same as one performed with the SEEK UP key.
The following table lists the operation corresponding to each key pressed during the seek operation (except

Description
SEEK UP
The SEEK UP key is used for auto-tuning (seek operation).
Pressing the SEEK UP key increases the frequency by one channel space and checks whether there is a
broadcasting station at each reception frequency (by a method determined depending on the states of the
ENAMIF and ENFMIF initial setting diodes). If a broadcasting station is detected, the seek operation ends.
The seek operation performed varies with the state of the AUTOLOC initial setting diode as follows:
(1) When AUTOLOC = 0 (with no auto local function):
A search operation begins at the frequency currently being received.
The search operation continues in local or DX mode whichever has been selected when the search
operation starts, until a station is detected.
(2) When AUTOLOC = 1 (with an auto local function):
A search operation begins at the frequency being currently received in local mode. When all frequencies are searched through in local mode, a search operation is switched to DX mode and continues
until a station is detected. If the SEEK UP key is pressed in local mode, DX mode is selected, and a
search operation restarts with the same frequency as for the previous search. If the SEEK UP key is
pressed during a search in DX mode, the search operation ends, and the frequency at which the
search operation began is selected.
When using the SEEK UP key, set the AUTO500 initial setting diode to 0. Setting it to 1 disables the
SEEK UP key.
The SEEK UP key functions during the search operation as follows:
Key
SEEK UP
When the SEEK UP key is pressed in seek-up mode, the seek operation stops,
and the frequency at which the search operation began is selected. If the auto
local function is being used when the key is pressed, local mode is switched.

MAN DWN
One of the following operations occurs depending on the state of the AUTO500
initial setting diode.
(1) When AUTO500 = 0:
A manual tuning operation begins at the frequency that is in the frequency
counter when the key is pressed.
(2) When AUTO500 = 1:
If the MAN UP key is pressed in seek-up mode, the seek operation stops,
and the frequency that was selected when the seek operation began is
reselected. If the auto local function is being used, local mode is switched.

6. REMOTE CONTROL FUNCTION
Use the µPD6121G for sending signals from a remote-controller. The µPD6121G incorporates a custom code.
If this code is not correctly set, the µPD17012GF-058 cannot be controlled using the remote controller.
The custom code which operates the µPD17012GF-058 is 8604H. Set the code to 8604H by connecting a diode
and a pull-up resistor appropriately on the key matrix of the µPD6121G. (See Section 6.4.)

APPENDIX COMMUNICATION WITH ELECTRONIC VOLUME CONTROL IC (I2C BUS INTERFACE)
The µPD17012-058 sends specified data, such as volume and balance data, to the electronic volume control IC.
Two buses, the data bus and clock bus, are necessary to output data to the electronic volume control IC. Data and
clock signals are output from the EVOL_DA pin (pin 2) and EVOL_SCK pin (pin 1) of the µPD17012-058.

NOTES FOR CMOS DEVICES
1 PRECAUTION AGAINST ESD FOR SEMICONDUCTORS
Note: Strong electric field, when exposed to a MOS device, can cause destruction
of the gate oxide and ultimately degrade the device operation. Steps must
be taken to stop generation of static electricity as much as possible, and
quickly dissipate it once, when it has occurred. Environmental control must
be adequate. When it is dry, humidifier should be used. It is recommended
to avoid using insulators that easily build static electricity. Semiconductor
devices must be stored and transported in an anti-static container, static
shielding bag or conductive material.
All test and measurement tools
including work bench and floor should be grounded. The operator should
be grounded using wrist strap. Semiconductor devices must not be touched
with bare hands. Similar precautions need to be taken for PW boards with
semiconductor devices on it.
2 HANDLING OF UNUSED INPUT PINS FOR CMOS
Note: No connection for CMOS device inputs can be cause of malfunction. If no
connection is provided to the input pins, it is possible that an internal input
level may be generated due to noise, etc., hence causing malfunction. CMOS
device behave differently than Bipolar or NMOS devices. Input levels of
CMOS devices must be fixed high or low by using a pull-up or pull-down
circuitry.
Each unused pin should be connected to VDD or GND with a
resistor, if it is considered to have a possibility of being an output pin. All
handling related to the unused pins must be judged device by device and
related specifications governing the devices.
3 STATUS BEFORE INITIALIZATION OF MOS DEVICES
Note: Power-on does not necessarily define initial status of MOS device. Production process of MOS does not define the initial operation status of the device.
Immediately after the power source is turned ON, the devices with reset
function have not yet been initialized. Hence, power-on does not guarantee
out-pin levels, I/O settings or contents of registers. Device is not initialized
until the reset signal is received. Reset operation must be executed immediately after power-on for devices having reset function.
