Description

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

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.

Normally, this pin is used to input radio mode

HOLD mode includes CLOCK STOP mode

Description

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).

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

(Min)). A built-in input amp and C

(0.2V

P-P

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

when the pin is set as an IN port.

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.

Description

Pins to which power is applied.

Normally, V

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 and

the program starts from address “0”. (power on

To operate the power on reset, the power

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.

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

h. The condition of the clock display is set as shown according to setting of the 12/24h jumper.

Without 12/24 jumper 12H display

With 12/24 jumper 24H display

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.

ALARM

1.Principal function

The alarm is set.

2.Key to be used

UP/HOUR key, DOWN/MIN key, MEMORY/CLOCK-ADJUSTMENT key, ALARM key, BUZR (p3-1) output.

3.Functions

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.
