MUTE

Muting output

port

1 bit output port. Normally, this port is used for

muting control signal output. This pin can set

the internal MUTE bit to "1" according to a

change in the input of I/O port 1. MUTE bit

output logic can be changed; PLL phase

difference can also be output using this pin.

HOLD

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

HOLD 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

HOLD pin. Memory back-up is

release when the

HOLD pin goes high in

MODE-0, or when the level of the

HOLD pin

low in MODE-1.

When memory back-up mode is entered by

executing a WAIT instruction, any change in

the

HOLD pin input releases the mode.

In memory back-up mode, current consumption

is low (below 10

µA), and all the output pins

(e.g., display output, output ports) are

automatically set to low level.

coupling allow operation at low-level input.

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

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

1 push/ 1 step tuning by UP/DOWN key.

When UP/DOWN key is pushed for more than 500ms, seek tuning is started.

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.

But seek tuning is not stopped even when a station was detected, in case UP/DOWN key is pushing

continue.

The scan time is 200ms/ step in TV/WB band. In other bands, it is 100ms/step.

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.

When the LW band received, manual tuning is 1kHz/step, but seek tuning is 9kHz/step.

In case of used SD signal.

PRESET MEMORY

1. Principal function

Calling and writing in preset memory.

2. Input ports and keys to be used.

0~9 keys, Minc key, Mdec key, MEMORY key, AM key, FM key, +5 KEYenable jumper.

3. Function

The each band have the fixed preset memory 10ch.

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.

When the Minc key is pushed, the preset memory called next ch.

When the Mdec key is pushed, the preset memory is decrement.

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.

The memory mode is set, when MEMORY key was pushed.

The memory mode is released automatically after 5 seconds.

The "MEMO" mark is flashed in the memory mode.

A receiving frequency is written in the fixed preset memory, when MEMORY key is pushed after 0~9 key

was pushed in the memory mode.

In case of Minc or Mdec key is used. It is selected the each ch in the memory mode, and you pushed

MEMORY key again.

a. The condition of the clock function is set as shown below according to setting of the CLOCK-dis jumper.

Without CLOCK-dis jumper: clock enable

With CLOCK-dis jumper: clock disable

b. The clock function is only the power off. So clock display and clock adjustment is not disable when power

is on.

c. If the MEMORY/CLOCK-ADJUSTMENT key is pushed in clock display, the clock adjusting enable state is

set for 5 second.

d. In that state, the hour of the clock is adjusted by pushing the UP/HOUR key, and the minute of clock is

adjusted by pushing the DOWN/MIN key.

e. If the UP/HOUR key, the DOWN/MIN key is not pushed for 5 seconds in clock adjusting enable state, that

state will be released. In this case, the second is not set the zero.

f. When the MEMORY/CLOCK-ADJUSTMENT key is pushed in the clock adjusting enable state, the second

of the clock is set to the zero and that state are released.

g. The minute or the hour step up by 1 step/1 push, when the UP/HOUR key or the DOWN/MIN key is pushed

for less than 500ms in clock adjusting enable state. The hour step up continuously by 1 step /250 ms by

UP/HOUR key is pushed for more than 500ms. the minute step up continuously by 1 step/150ms by the

[DOWN/MIN] key is pushed for more than 500ms

i. The condition of the how many clocks is set as shown below according to setting of the DUAL-dis, jumper.

Without DUAL-dis. jumper: 1 clock

With DUAL-dis. jumper: 2 clocks

In case of 2 clocks, the clocks have minute in common, so it can change only hour. The clock changed to

clock1 or clock2 by BAND-DUAL key.

a. When the clock is disable, the alarm is disable.

b. The alarm is enable when power is on and power is off.

c. If the ALARM key is pushed. The alarm adjusting enable state is set for 5 seconds, and the alarm times flash

at 1 Hz rate.

In that state, the hour of the alarm is adjusted by pushing the UP/HOUR key, and the minute of alarm is

adjusted by pushing the DOWN/MIN key.

d. If the any keys are not pushed for 5 seconds, the alarm adjusting enable state will be released.

e. When the MEMORY/CLOCK-ADJUSTMENT key is pushed in the alarm adjusting enable state, that state is

released and alarm times is changed flash to on. So if the any keys are not pushed 5 seconds, the alarm

display state is released.

f. The hour or the minute step up by 1 step/ 1 push, if the key is pushed for less than 500ms in alarm adjusting

enable state.

If the key is pushed more than 500 ms in this state, the hour step up continuously by 1 step/ 250ms, the

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.
