The input and output of these 4 bit I/O ports

Input and output may be programmed in 1 bit
units. Pins P2-1 through P2-2 can also be used
for analog input to the built-in 6 bit, 2-channel
A/D converter.
Conversion time of the built-in A/D converter
using the successive comparison method is
280µs. The necessary pin can be programmed
to A/D analog input in 1 bit units, and P2-3 can
be set to the reference voltage input. Internal
power supply (V

addition, constant voltage (V

2 bit I/O ports, whose input/output can be
programmed in 1 bit units.
The P3-1 pin also functions as the output for

Description
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.
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

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
reset).(Note)
To operate the power on reset, the power
supply should start up in 10~100ms.
