for the I C bus serial data.
In TEST mode, used as the input pin
for the signal to be compared by the
phase comparator.

Normally used as the I C bus serial
clock input.
In TEST mode, used to input the
reference signal of the phase
comparator.

The circuit configuration is open
collector output. Each pin has a
built-in comparator. The status of the
comparator can be checked in READ
mode.
In TEST mode, P7 is a counter output
which allows counter operation to be
checked.

FUNCTION
P6
Output can be controlled by setting
the band switch data.
The circuit configuration is open
collector output.
An A / D converter is built in. In READ
mode, five levels of applied voltage
can be read.
In TEST mode, outputs the reference
signal derived by dividing the crystal
OSC signal by the set divider ratio.
This allows operation to be checked.
P3
Basically used as the address setting
pin. The sub-address can be changed
by applied voltage.
Can be used as a band switch as
well, but incorporates resistance
(12kΩ) for limiting current.
11
P0
Output can be controlled by setting
the band switch data. Incorporates
resistance (12kΩ) for limiting current.
(Can also be used for setting the
prescaler in TEST mode.)

When using the device at temperatures higher than 25°C, maximum power dissipation decreases for every
1°C as follows : 4.3mW with F-type : 4.5mW with FN-type.
Do not set the port pins (Pins 6, 7, 8, 9, 10, and 11) at or lower than the level of the GND pin.
These devices are easy to be damaged by high static voltage or electric fields.
