DESCRIPTION
Input:
<
FM_BandSelect >
Selects the FM band on the rising edge of the signal.
Users can select the band by pressing the local BAND
button on the TV/FM Tuner; or from a remote button
defined on a touchpanel or other interface.
This signal is interlocked with the TV, AM and WX
band selection inputs (on slots 2 and 3). That is, only
one band can be selected at a time. The band will be
set to whichever <BandSelect> input goes high last.
High/1 = Select FM band; Low/0 = Exit FM band
Output:
<
FM_BandSelect-F >
Indicates that the FM band has been selected either
via the local BAND button or from a remote button
defined on a touchpanel or other interface.
High/1 = FM band selected;
Low/0 = FM band not selected
Output:
<
FM_Mono-F >
Indicates that the FM tuner is in the mono state. When
low, indicates that the tuner is operating in stereo.
The tuner will go into the mono state whenever the
<
FM _ Mono > input is high.
High/1 = In FM mono mode; Low/0 = In FM stereo
Inputs:
<
FM_ >,
< FM_Station- >
Tunes the FM station up (+) or down (+) on the rising
edge of the signal when the FM band is selected.
Users can tune to stations by pressing the local up (
k
)
and down (
j
) buttons on the TV/FM Tuner when the
unit is in TUNE mode; or from remote buttons defined
on a touchpanel or other interface.
If the input is high for longer than 300 milliseconds, the
tuner will continue to tune from station to station until:
1) the input goes low (the local or remote button is
released); or
2) it wraps around to the original station.
The tuner will jump in 100 kHz steps if in US mode; or
in 50 kHz steps if in European mode. The step rate is
selected via the <
FM_US/Europe > input.
High/1 = Change station (tune button pressed);
Low/0 = Stop station changing (tune button released)
Input:
<
FM_US/Europe >
Selects the FM frequency step rate.
When low, the frequency is set to US steps (100 kHz).
When high, the frequency is set to European steps (50
kHz).
The tuner stores the last frequency selected in the
EEPROM. On power-up, it restores this value.
High/1 = European mode; Low/0 = US mode
