Sa~Sh: Fluorescent display segment signals
K, ~K4: Key input, diode matrix input
CLOCK, CE, DATA IN, DATA OUT: Signals transferred to
PLL IC LC7218
SD IN: Station detector signal input
When the SD IN pin becomes “LOW” as regards a
frequency band, the STRQ pin (LC7218 OUT2) becomes
“HIGH” so that PLL IC performs IF counting. As a result
of this, when FM 10.7 MHz +10 kHz, MW 450 kHz +3 kHz
or LW 450 kHz +0.6 kHz is obtained, “TUNED” lights,
while when in the auto tuning mode, the station scanning
stops.
