Output condition switching input terminal.
This terminal sets the display output mode
(LED, FL, or LCD).

FL ...Make this terminal “L” level.
LCD...Apply AC voltage to this terminal.
7-segment drive output terminal.
This output terminal for enabling display of the
digit corresponding to units of 100 kHz in the FM
mode and the digit corresponding to units of 1
kHz in the AM mode.
Receiving frequency data input terminal. Power supply terminal (5V).
A data signal containing the receiving frequency
and band is sent to this terminal from pin 22 of
C7 (RVITC9137P) each time the receiving
frequency is changed.

A data signal is composed of 16 bits. Eleven bits
are assigned for frequency data and the remain-
ing 5 bits are assigned for the reception bands.
Receiving frequency data input control timing
input terminal.
Each time a data signal is sent, a timing signal is
concurrently sent from pins 20 and 21 of IC7 to
this terminal, to read the data signal.
Two lines (CK-1 and CK-2) are used for timing
the data signal reading. They have the following
timing relationship with the data signal.
Segment drive output terminal.
This output terminal enables display of the digit
corresponding to units of 100 MHz in the FM
mode and the digit corresponding to units of
1000 kH in the AM mode.
7-segment drive output terminal.
This output terminal enables display of the digit
corresponding to units of 10 MHz in the FM
mode and the digit corresponding to units of 100
kHz in the AM mode.
7-segment drive output terminal.
This output terminal enables display of the digit
