Scans through TV stations on the rising edge of
the input.
Users can scan for stations by pressing the local
Up and Down buttons on the TV/FM Tuner when
the unit is in SCAN mode; or from remote buttons
defined on a touchpanel or other interface.
The tuner will scan up (+) or down (-) to a station,
pause for five seconds, then continue scanning to
the next station. Pressing the local or remote scan
button again will stop the Scan operation.
The Scan operation also stops when:
1) a local BAND or MODE button is pressed; or
2) a remote band or search button is pressed; or
3) it wraps around to the original station; or
4) after a maximum number of repeats; or
5) a station is directly entered; or
6) a remote scan +/- or s/- button defined
on a touchpanel or other interface is pressed.
High/1 (rising edge) = Scan up or down;
Low/0 = No effect
Output:
<
TV_Mute-F >

produce a clear signal, and the < TV_Mono >
input is low.
