b. When a cassette tape is loaded (Fig. 21)
When a cassette tape is loaded during tuner operation,
"tape operation request" data is passed from the deck
controller to the system
controller.
When
the system
controller receives this data, a 'tuner stop'' command
is
passed to the tuner controller, and after data indicating
that the "'tuner has stopped" is received from the tuner
wa
controller, a 'tape operation'' command
is passed to the
deck controller. Hence, the set is switched automatically
from
tuner
to tape
when
a cassette
tape is loaded.
