Description of Key Matrix
2.3.1
Initialization switches
The initialization switches determine the functions of the
μ
PD178024GC-051. Be sure to set these switches.
The following 15 types of initialization switches are available. All these switches are read on power application to
the device, on releasing the standby mode, and on resetting the
μ
PD178024GC-051; they are ignored at all other
times.
To read an initialization switch, the corresponding initialization switch input pin (pin 49 to 56) is tested every 10
ms, and if a specific status of the pin is detected three times, the status of the initialization switch is read. In this way,
chattering is eliminated.
(1) Switches specifying the intended region of the set
AREA1, AREA2
(2) Switch specifying whether the intermediate frequency is used for broadcasting station detection
during auto tuning of the AM band (MW, LW) of the radio
DISAMIFC
(3) Switch setting the intermediate frequency of the AM band (MW, LW) of the radio
AMIF
(4) Switch specifying whether the clock function is used
NOCLK
(5) Switch setting the 12-hour/24-hour mode of the clock
CLK12
(6) Switch specifying whether an equalizer IC (TA2078P) is used or not
EQICSEL
(7) Switch specifying whether the fader adjustment function by an electronic volume IC (TDA7313) is used
or not
FADSEL
These switches are set by pulling up or down the corresponding pins.
The functions of the initialization switches are explained next in alphabetical order.
