Description
HOLD mode control input;
Input pin for request/release HOLD mode.
Normally, this pin is used to input radio mode selection signals or battery detection
signals.
HOLD mode includes CLOCK STOP mode (stops crystal oscillation) and WAIT mode
(halts CPU). Setting is implemented with the CKSTP instruction or the WAIT
instruction. When the CKSTP instruction is executed, request/release of the HOLD
mode depends on the internal MODE bit. If the MODE bit is “0” (MODE•0), executing
the CKSTP instruction while the
pin is at low level stops the clock generator

and the CPU and changes to memory back•up mode. If the MODE bit is “1” (MODE•
1), executing the CKSTP instruction enters memory back•up mode regardless of the
level of the
pin. Memory back•up is release when the
pin goes high in
HOLD
HOLD
MODE•0, or when the level of the
pin low in MODE•1.
HOLD
When memory back•up mode is entered by executing a WAIT instruction, any
change in the pin input releases the mode.
HOLD
In memory back•up mode, current consumption is low (belowmA1),0 and all the
output pins (e.g., display output, output ports) are automatically set to low level.
TEST mode control input;
Input pin used for controlling TEST mode. High level indicates TEST mode, while low
level indicates normal operation. The pin is normally used at low level or no•
connection (NC). (A pull•down resistor is built•in).
48
TEST
IF signal input/Input port;
IF counter’s IF signal input for counting the IF signals of the FM and AM bands and
detecting the automatic stop position.
The input frequency is between 0.35~12MHz (0.2VP•P(Min)). A built•in input amp
and C coupling allow operation at low•level input.
50
IFIN/IN
The IF counter is a 20 bit counter with optional gate times of 1, 4, 16, and 64ms. 20
bit of data can be readily stored in memory.
This input pin can be programmed for use as an input port (IN port). CMOS input is
used when the pin is set as an IN port.

Phase comparison output;
51
52
DO1/OT
PLL’s phase comparison tri•state output pins.
When the programmable counter’s prescaler output is higher than the reference
frequency, output is at high level. When output is lower than the reference frequency,
high impedance output is obtained.
Because DO1 and DO2 are output in parallel, optimal filter constants can be
designed for the FM/VHF and AM bands. Pin DO1 can be programmed to high
impedance or programmed as an output port (OT). Thus the pins can be used to
improve lock•up time or used as output ports.

In back•up mode (when CKSTP instructions are being executed), voltage can be
lowered to 1.0V. If voltage falls below 1.5V while the CPU is operating, the CPU
stops to prevent malfunction (STOP mode). When the voltage rises above 1.5V, the
CPU restarts.
STOP mode can be detected by checking the STOP F/F bit. If necessary, execute
initialization or adjust clock by program.
When detecting or preventing CPU malfunctions using an external circuit, STOP
mode can be invalidated and rendered non•operative by program. In that case, all
four bits of the internal TEST port should be set to “1”.

If more than 1.8V is applied when the pin voltage is 0, the device’s system is reset

To operate the power on reset, the power supply should start up in 10~100ms.
FM programmable counter input;
Programmable counter input pin for FM,VHF band.
The 1/2+pulse swallow system (VHF mode) and the pulse swallow system (FM
mode) are selectable freely by program. At the VHF mode, local oscillation output
(VCO output) of 50~230MHz (0.2VP•P(Min)) is input and FM mode, 40~130MHz
(0.2VP•P (Min)) is input. A built•in input amp and C coupling allow operation at low•
level input. (Note) when in the PLL OFF mode or when set to AMIN input, the input is
pulled down.

AM local oscillator signal input;
Programmable counter input pin for AM band.
The pulse swallow system (HF mode) and direct dividing system (LF mode) are freely

Voltage doubler boosting pin for driving the LCD.
A capacitor (0.1mF Typ.) is connected to boost the voltage.
The VLCD pin outputs voltage (3.0V), which has been doubled from the constant
voltage (VEE: 1.5V) using the capacitors connected between C1 and C2. That
potential is supplied to the LCD drivers. If the internal VLCD OFF bit is set to “1” by
program, an external power supply can be input through the VLCD pin to drive the
LCD.

EE
A stabilizing capacitor (0.1mF Typ.) is connected. This is a reference voltage for the
A/D converter, key input, and the LCD common output’s bias potential.
Note: 1. When the device is reset (voltage higher than 1.8V, or when RESET =low® high), I/O ports are set to input,
the pins for I/O ports and additional functions (e.g., A/D converter) are set to I/O port input pins, while
the IFIN/IN pins become IF input pins.
2. When in PLL OFF mode (when the three bits in the internal reference ports all show “1”), the IFIN and
FMIN, AMIN pins are pulled down, and DO1 And DO2 are at high impedance.
3. When in CLOCK STOP mode (during execution of CKSTP instruction), the output port and the LCD
output pins are all at low level, while the constant voltage circuit (VEE), the voltage doubler circuit (VLCD),
and the power supply for the crystal oscillator (VXT) are all off.
4. When the device is being reset, the contents of the output ports and internal ports are undefined and
initialization by program is necessary.

MANUAL TUNING/SEEK TUNING
1. Principal function
1 push/ 1 step and seek tuning.
2. Input ports and keys be used.
UP key, DOWN key
3. Function
a. 1 push/ 1 step tuning by UP/DOWN key.
b. When UP/DOWN key is pushed for more than 500ms, seek tuning is started.
c. The seek tuning is stopped. If IFcount•enable jumper is “ON”, the stop signal specified is input on IF
INPUT, else IFcount•enable jumper is “OFF”, the stop signal specified is input on SD INPUT.
d. But seek tuning is not stopped even when a station was detected, in case UP/DOWN key is pushing
continue.
e. The scan time is 200ms/ step in TV/WB band. In other bands, it is 100ms/step.
f.
The tuning method is the saw tooth wave form method, and when the receiving frequency rearch the
band edge, if goes to the opposite side and the continuous tuning is hold for 500ms. In case of meter
band, refer explanation of the meter band.
g. When the LW band received, manual tuning is 1kHz/step, but seek tuning is 9kHz/step.
h. In case of used SD signal.

3. Function
a. The each band have the fixed preset memory 10ch.
b. The fixed preset memory is called when 0~9 was pushed.
Incase of +5 KEYenable jumper is set, the +5 key at first pushing is only flashing “+5” mark. A preset
memory number is fixed when 1~5 key was pushed during “+5” mark is flashed. If second pushing is
nothing for 5 second, it canceled “+5” mark flashing mode.
c. When the Minc key is pushed, the preset memory called next ch.
When the Mdec key is pushed, the preset memory is decrement.
d. In case of +5KEYenable jumper is off, when the AM or FM key is used. Frequency is setting direct. AM or
FM key push, changed the direct input mode, and frequency is setting by pushed 0~9 key. If input
frequency is inside. The frequency is received, but the frequency is outside, the “Err” mark is flashed, and
canceled this mode.
e. The memory mode is set, when MEMORY key was pushed.

minute step up continuously by 1 step/150ms.
g. If alarm time comes same to clock time, the alarm sound is output by BUZR (p3•1) port. In that state if the
any keys are pushed, the alarm sound is released. But if the any keys are not pushed, the alarm sound is
output for 60 minutes.

HANDLING MOS DEVICES:
Electrostatic charges can exist in many things. All of our MOS devices are internally protected against
electrostatic discharge but they can be damaged if the following precautions are not taken:
· Persons at a work bench should be earthed via a wrist strap.
· Equipment cases should be earthed.
· All tools used during assembly, including soldering tools and solder baths, must be earthed.
· MOS devices should be packed for dispatch in antistatic/conductive containers.
