2.6 Description of the Key Matrixes
2.6.1 Initial setting diode matrixes
The µPD17012GF-058 has the following 18 initial setting diode matrixes. When the VDD is supplied with power
for the first time (at a power-on reset), the states of the diodes in these matrixes are read in. In all other occasions,
they are ignored.
(1) Switches to specify the reception area
AREA1, AREA2, and AREA3
(2) Switches to specify the reception band
DISFM3, DISLW, ENFM, and ENMW2
(3) Switch to specify whether to use the auto-storage function
DISAMEMO
(4) Switches to specify whether to use the frequency counter for detecting broadcasting stations
ENAMIF and ENFMIF
(5) Switch to specify tuning operation
AUTO500
(6) Switches to specify display priority
PRIO1 and PRIO2
(7) Switches to specify the clock function
CLKDISP, FLASH, and NOCLK
(8) Switches to specify the tape function
KTAPE
(9) Switch to specify the mute output
MUTESEL
(10) Switch to specify the local operation
AUTOLOC
(11) Switch to specify the intermediate frequency for the AM (MW, LW) band
IFAM
(12) Switch to specify whether the MW band stereo reception function is available
MWS
(13) Switch to specify that the standby mode has no clock
