No. ID-9042) Date Published November 1994 P Printed in Japan © 1994 µPD17006AGF-011 FUNCTIONAL OUTLINE Receive frequency, channel space, reference frequency, intermediate frequency Parameter Receive frequency Channel space Reference frequency Intermediate frequency FM 87.50-108.00 MHz 50 kHz 50 kHz 10.7 MHz MW 522-1620 kHz 9 kHz 9 kHz 450 kHz 459 kHz 10.71 MHz LW 144-281 kHz 1 kHz 1 kHz 450 kHz 459 kHz 10.71 MHz Band Station selection function (1) Manual tuning Type Description Manual up Manual down Increases or decreases frequency by 1 step each time key is pressed. If key is held down for 0.5 second or longer, frequency is increased/decreased rapidly until key is released. (2) Auto tuning Type Seek up Seek down Description Searches station in up or down direction. When station is found, its frequency is held (seek operation is performed in 100-kHz steps in FM band). Only RDS stations are searched for in RDS mode. Only traffic information station is searched for in TP/SK mode. (3) Preset memory Five stations can be stored for each of the four bands (FM1, FM2, FM3, and AM). Therefore, up to 20 stations can be stored. The AM band is shared with MW and LW bands. (4) Preset memory scan The contents of the FM1, FM2, FM3, and AM preset memories can be received independently for about 5 seconds each. (5) Auto store memory Stations can be searched starting from the minimum frequency. When stations are found, they are written to the preset memories starting from the one with the highest signal meter level. The stations are then sorted in the order of frequency. (6) Last channel memory One station of last channel memory is provided independently for each of FM1, FM2, FM3, and AM. (7) Auto retune If the SD signal cannot be detected for about 20 seconds while a station is being received, tuning is automatically started. 2 µPD17006AGF-011 RDS function (1) Broadcasting station display The name of the broadcasting station currently being received is displayed by using a PS code. (2) AF operation An AF list of up to 25 stations can be loaded, with METHOD A and METHOD B supported. Loading of AFs of other stations by EON is also supported. (3) Traffic information station selection TA and TP bits are detected in TP/SK standby status and a traffic information station is selected. This function supports EON. (4) Time adjustment The internal timer is adjusted by using CT code. (5) Alarm When the PTY alarm code (=31) is received, the sound is changed to the radio. (6) RDS memories Up to 22 types of PI codes can be stored in the RDS memories. The memory of each PI code stores eight stations from the corresponding AF lists. (7) Broadcasting program identification information By using PTY codes 0 to 15, the name of the broadcasting program currently being received can be displayed. In addition, searching by using the displayed program name can be performed. Timer function (1) 12-hour display (with “ ” and “ ” displayed) and 24-hour display (2) Flashing (1 Hz) of the colon (“:”) can be enabled or disabled. (3) Low-current backup is possible in non-timer mode. Tape function (1) Sound selection can be made by tape signal input. (2) Tape running direction can be displayed. (3) Noise reduction output can be performed. CD function (1) Sound selection can be performed by CD signal input. (2) Sound selection can be performed by CD key. 3 µPD17006AGF-011 IC (P0C0) IC (P0C1) PANEL (P0C2) DK (P0C3) SK (P0D3) SD (P0D2) DEV.

One key can be independently assigned to preset memories storing five stations in each of the FM1, FM2, FM3, and AM bands, totaling 20 stations. If a station written to preset memory is an FM-band RDS broadcasting station, the PI code of that station is also written at the same time. If a station is called for which RDS broadcasting is stored, AF selection is performed by using the AF list of preset 8 stations. If RDS broadcasting still cannot be received, a PI seek operation is performed in the up direction. If SEEK/MAN DOWN key is pressed during this seek operation, a normal seek operation is performed and continued until a station is found. To stop the seek operation, press the SEEK/MAN UP key. During a time or PS display, the frequency display is switched to. Operation Description ● When MESEL switch of initial setting diode = 1 (shorted with diode) Preset memory is write-enabled for about 5 seconds when ME key is pressed. By pressing any of the to keys during M5 M1 this period, the frequency currently being received is written to preset memory corresponding to the pressed key. Frequency cannot be written if the ME key is held down. When frequency is written, a beep sound is issued for about 40 ms. ● When MESEL switch of initial setting diode = 0 (open) By pressing any of to keys for about 2 seconds, M1 M5 M1 M2 M3 Write M4 frequency currently being received is written to preset memory correspondM5 ing to the pressed key. ME key is invalid. Same operation is performed when same preset memory key is pressed while contents of current preset memory are being received. When frequency is written, a beep sound is issued for about 40 ms. ● When MESEL switch of initial setting diode = 1 (shorted with diode) By pressing any of the to keys when preset M1 M5 memory is not write-enabled, contents of preset memory corresponding to the pressed key are called. Call ● When MESEL switch of initial setting diode = 0 (open) By pressing any of the to keys and then releasing M1 M5 the key within seconds, contents of preset memory corresponding to the pressed key are called. When same preset memory key is called while contents of preset memory are currently called, a beep sound is issued for about 40 ms. 16 µPD17006AGF-011 Symbol Functional Description Following frequency is written to the to M1 M5 keys on power application so that the set can be easily adjusted: Preset memory number M1 M2 M3 M4 M5 FM1 (MHz) 87.50 89.90 97.90 105.90 107.90 FM2 (MHz) 87.50 87.50 87.50 87.50 87.50 FM3 (MHz) 87.50 87.50 87.50 87.50 87.50 AM (kHz) 144 153 522 603 1404 Band (2) Shift mode When any of the M1 M1 to M5 keys is pressed in shift mode, and when FUNC of initial setting diode = 1, the pressed key serves as a double function key. Function key assigned to each of the M1 to M5 keys is shown below. M2 For operation of each key, refer to description of the key. When FUNC of initial setting diode = 0, function key is invalid.

Local (LOCAL/DX) control key M4 M5 Refer to LOC key. Tape noise reduction key Refer to NR key. 17 µPD17006AGF-011 Symbol Functional Description These keys are used to increment/decrement receive frequency while frequency is displayed and, in combination with DISP key, to adjust timer while time is displayed. (1) During frequency display Each time SHIFT key is pressed, manual tuning function and auto tuning function are alternately selected. When auto tuning function is selected (not in shift mode), “AUTO” on LCD panel lights. When this key is pressed while auto tuning function is selected and while time or PS is displayed, frequency is displayed. If no station is assigned to frequency at which seek operation has been stopped, frequency (last channel) at which seek operation was started is displayed again. Even if mode is changed between tape/CD and radio modes during seek operation, seek operation continues. If mode is changed between radio mode to tape/CD mode at this time, tape/CD is displayed for about 3 seconds. If seek operation still continues after that, frequency is displayed. When auto tuning of FM band is performed, frequency is incremented/decremented in 100 kHz units. In manual tuning mode, it is incremented/decremented in 50 kHz units. ● SEEK/MAN UP Normal mode Frequency is incremented ( SEEK/MAN UP key) or decremented ( SEEK/MAN DOWN key) 1 channel space at a time, and presence/absence of broadcasting station (SD + IF count or SD: depending on IF/ SD switch of initial setting diode) is detected for each receive frequency. SEEK/MAN DOWN If presence of station is detected, frequency of station is held. ● RDS seek in FM band When presence of station is detected, RDS pin (pin 10) is checked. If RDS signal is input within about 500 ms, input of RDS data is started. When RDS data has been input, its frequency is held. If RDS data is not input within about 1.5 seconds, seek operation continues. If RDS signal is missing, seek operation continues. ● PTY seek in FM band When presence of broadcasting station is detected, whether it is an RDS station is judged. If RDS data is input, its PTY is checked. If PTY is different from that expected, seek operation continues. If PTY matches, its frequency is held. ● TP/SK seek in FM band When presence of station is detected, whether it is an RDS station is judged. When RDS data is input, TP bit is checked. If traffic information station is being received, its frequency is held. If station is not traffic information station, seek operation continues. If RDS signal is missing, SK pin is checked. If SK signal is present, its frequency is held. If not, seek operation continues. 18 µPD17006AGF-011 Symbol Functional Description During seek operation, operation of each key is as follows: Key Operation M1 ~ Stops seek operation. Calls contents of preset memory corresponding to pressed key. M5 ● In normal mode Stops seek operation. • SEEK/MAN UP SEEK/MAN UP key during seek up and SEEK/MAN DOWN key during seek down Stops seek operation and calls frequency before seek operation. • SEEK/MAN DOWN SEEK/MAN DOWN key during seek up and SEEK/MAN UP key during seek down Operation of pressed key is started from frequency at which key is pressed. ● In shift mode Starts manual up/down operation from frequency at which key is pressed. SEEK/MAN UP TP/SK LOC SEEK/MAN DOWN Seek operation continues. LOUD Operation of pressed key is started. SHIFT RDS PSCAN/ASM Seek operation is stopped. Operation of pressed key is started. BAND Analog keys other than above are invalid. ● Shift mode When manual tuning function is effected, frequency is incremented by 1 step (1 channel space) when SEEK/MAN UP key is pressed, or decremented by 1 step when SEEK/MAN DOWN key is pressed. If key is held down for more than 0.5 second, frequency is incremented/decremented in fastforward mode at rate of about 40 ms/step, until key is released. If key is held down while manual tuning function is in effect, all other keys are invalid. When time of PS is displayed, frequency is displayed instead. (2) During time display When SEEK/MAN UP DISP If DISP or SEEK/MAN DOWN key is pressed while time is displayed and while key is pressed, hour digits and minute digits can be adjusted. key is not held down, frequency display is switched to and operations that are normally performed while frequency is displayed are performed. 19 µPD17006AGF-011 Key Functional Description • Hour digit adjustment Each time SEEK/MAN DOWN key is pressed, hour advances by 1 hour. If key is held down for more than 0.5 second, hour is incremented in fast-forward mode by 1 hour every 200 ms, until key is released. Minute digits and second count value are not affected. SEEK/MAN UP • Minute digit adjustment Each time SEEK/MAN UP key is pressed, minute advances by 1 minute. If key is held down for more than 0.5 second, minute is incremented in fast-forward mode by 1 minute every 100 ms, until key SEEK/MAN DOWN is released. No carry to hour digit occurs. Each time adjustment is made, second counter is reset. During adjustment, colon remains lighted. When MESEL switch of initial setting diode = 1 (shorted with diode), this key is used to enable preset memory to be written. When data is written to preset memory, beep sound is issued for about 40 ms. This key is invalid when MESEL switch = 0 (open). ● During frequency display This key is used to enable preset memory to be written. When this key is pressed, data can be written to preset memory for about 5 seconds from point at which key is pressed. By pressing any of the to M1 keys, currently re- M5 ceived frequency is written to preset memory corresponding to pressed key. If ME key is held down at this time, frequency cannot be written. In memory write-enable status, operation of each key is as follows: ME Key Operation Cancel memory write-enable status. ~ M1 When any of these keys is pressed, currently received frequency is written to preset memory corresponding to pressed key. Mute output is not performed. M5 For details, refer to description of the M1 to M5 keys. Cancel memory write-enable status. If this key is held down for about 2 seconds, auto store memory operation is PSCAN/ASM performed. If it is pressed less than 2 seconds, preset memory scan operation is performed. SEEK/MAN UP SEEK/MAN DOWN ME 20 Cancel memory write-enable status. Operation of pressed key is started from current frequency. Cancels memory write-enable status. µPD17006AGF-011 Key Operation Key Operation • FM band Cancels memory write-enable status. Performs operation of TP/SK key. TP/SK • Other band Invalid key. LOC DISP ME SHIFT Cancel memory write-enable status. Operation of pressed key is performed. BAND LOUD • FM band Cancels memory write-enable status. Performs operation of pressed key. RDS • Other band Invalid key. Analog keys other than above are invalid. When this key is held down for 2 seconds or longer, auto store operation is performed; when it is pressed less than 2 seconds, preset memory scan operation is performed. If time or PS is displayed, frequency is displayed instead. ● Preset memory scan Preset memories are sequentially called 5 seconds each starting from preset memory M1 if station PSCAN/ASM outside of current preset memory is being received, or from next preset memory if preset memory is being received (e.g., from M4 if M3 is received), as illustrated below. M1 → M2 → M3 → M4 → M5 When next preset memory is called after hold period of 5 seconds, beep sound is issued for about 40 ms. 21 µPD17006AGF-011 Symbol Functional Description Operation of each key is as follows while preset memories are being scanned: Key PSCAN/ASM Operation ● If released within 2 seconds Preset memory scanning is stopped, and frequency at which key was pressed is held. ● If held down for 2 seconds or more Preset memory scanning is stopped, and auto store memory operation is started. Stop preset memory scanning. ~ M1 Call contents of preset memory corresponding to pressed key. M5 However, nothing can be written to preset memory. SEEK/MAN UP SEEK/MAN DOWN BAND Stop preset memory scanning. Operation of pressed key is started from frequency at which key was pressed. Stops preset memory scanning and selects band. TP/SK LOC Continue preset memory scanning. LOUD Operation of pressed key is performed. SHIFT RDS PSCAN/ASM Analog keys other than above are invalid. ● Auto store memory Searches broadcasting stations in DX mode in range from lower limit (minimum frequency) to upper limit (maximum frequency) of currently received band, writes preset number of stations starting from one with highest signal meter level, and then sorts stations in order of frequency. In this case, if RDS broadcasting is received in FM band, the PI code of that station is also recorded at the same time. If stations having same PI codes are found, only station with highest signal meter level is written. After operation, M1 is received. If no station is found, frequency at which operation was started is resumed. (a) If stations have been written to all the keys M1 through M5 and then another station is found If signal meter level of that station is lower than signal meter level of station written to M5, selection operation continues. If signal meter level is higher, that station is written to M5, stations written to M1 to M5 are sorted again starting from highest signal meter level, and then selection operation continues. If stations with same signal meter level are found, it is assumed that signal meter level of station found first is higher. (b) If number of stations falls short of number of preset stations Stations found so far are sequentially written to preset memory starting from M1, and found stations are sorted in order of frequency. Contents of remaining preset memory before auto store memory operation was performed are preserved. 22 µPD17006AGF-011 Symbol Functional Description Press this key again to stop auto store memory operation. Stations so far found are written to preset memories and sorted in order of frequency. If number of stations found is less than 5, remaining preset memory peserves previous contents. PSCAN/ASM If operation mode is changed during auto store memory operation, stations found so far are written to preset memories and sorted in order of frequency. If number of stations found is less than 5, remaining preset memory preserves previous contents. During auto store memory operation, keys other than PSCAN/ASM , CD , and SHIFT are invalid. This key selects function of double function key and tuning function when FUNC of initial setting diode = 1. SHIFT Each time this key is pressed while frequency is displayed, manual tuning and auto tuning functions are alternately selected. At this time, output of SHIFT pin (pin 56) is also alternately changed between low and high levels. SHIFT pin outputs high level as default value. This key selects received band in tuner mode. Default band is FM1. Each time this key is pressed, band is changed as follows: FM1 → FM2 → FM3 → AM Outputs of BAND 0 and BAND 1 pins are changed as follows, depending on received band: BAND Pin BAND 0 BAND 1 FM 1 × MW 0 0 LW 0 1 Received band (0 : low level, 1 : high level, × : Don’t care) When band is changed, frequency is displayed. Turns ON/OFF RDS mode. When RDS mode is ON, “RDS” on LCD panel lights. When RDS mode is ON, following processing is performed: RDS ● AF selection during on air ● PI search This operation is performed when AF selection operation takes place when CE reset, band selection, or preset memory read is carried out and when AF selection operation fails. ● Only RDS stations are detected during auto seek. PS display and RDS data input are performed regardless of whether RDS mode is ON/OFF. 23 µPD17006AGF-011 Symbol Functional Description (1) When pressed for less than 0.5 second Changes display or adjusts timer. ● Display selection function Each time this key is pressed, display is changed as follows: (a) When PRIDISP = 0 (open) • Tape/CD mode --- --- TAPE/CD → (PS) → Frequency → Time ----------- After 5 seconds • Tuner mode --- --- (PS) → Frequency → Time ----------- DISP (LOUD) After 5 seconds Each time key is pressed, display is changed as indicated by solid arrow. However, PS code is displayed when PS code is input. When PS code is input, and key is not input within 5 seconds after frequency DISP display, PS display is selected as indicated by dotted line. Caution Frequency display after tuning is changed to PS display as soon as PS code has been input. (b) When PRIDISP = 1 (shorted with diode) and PS is present • Tape/CD mode After 5 seconds --- --- ------------------------ ----------- After 5 seconds 24 --- ----- --- TAPE/CD → PS → Frequency → Time ----------- After 5 seconds µPD17006AGF-011 Symbol Functional Description • Tuner mode After 5 seconds --- --- ------------------------ --- --- PS → Frequency → Time ----------- After 5 seconds (c) When PRIDISP = 1 (shorted with diode) and PS is absent • Tape/CD mode After 5 seconds --- --- ------------------------ --- --- TAPE/CD → Frequency → Time ----------- After 5 seconds DISP (LOUD) • Tuner mode --- --- Frequency → Time ----------- After 5 seconds Each time this key is pressed for less than 5 seconds, display is changed as indicated by solid arrow. If DISP key is not input for 5 seconds or more, display is changed as indicated by dotted line. (2) When pressed for 0.5 second or more Loudness is turned ON/OFF. Each time this key is pressed for 0.5 second or more, output of LOUD pin (pin 72) is inverted (default status is low level). When loudness is ON, “LOUD” on LCD panel lights. This is local (LOCAL/DX) control key. Each time this key is pressed, setting of LOCAL/DX is toggled. LOC If local setting is made during seek operation, LOCAL pin (pin 69) outputs high level. On power application, DX setting is assumed (LOCAL pin outputs low level). When local setting is made, “LOC” on LCD panel lights. 25 µPD17006AGF-011 Symbol Functional Description Turns ON/OFF forced monaural. Forced monaural is turned OFF as default condition. MONO pin outputs high level, and “MONO” on LCD panel goes off. MONO When this key is pressed, MONO pin outputs low level, and “MONO” on LCD display lights. At this time, “STEREO” is forcibly extinguished. This key is valid only in FM mode. In AM mode, MONO pin is fixed to low level. Operation continues even if band, frequency, or mode is changed. When this key is pressed, original setting is resumed. Turns ON/OFF TP/SK mode. As traffic information identification signal, TP and TA bits of RDS, and SK and DK signals are used. When TP/SK mode is ON, “TP/SK” on LCD panel lights. This key is invalid in a band other than FM. Operation Normal or RDS mode ↑ ↓ TP/SK mode or RDS + TP/SK mode If station is found during auto tuning in TP/SK mode, TP bit of RDS is checked. If TP bit cannot be detected, SK signal is checked. In TP/SK mode, following operation is performed if traffic information station identification signal is missing: TP/SK (1) During normal reception Traffic information identification signal is checked. If it is missing for 30 consecutive seconds, SK mute signal is output. If traffic information identification signal is still missing for 3 more seconds, traffic information alarm is output. SK mute and traffic information alarm are continuously output until traffic information identification signal is detected. If traffic information identification signal is detected in this process, output of SK mute and traffic information alarm is stopped. (2) During tuning operation Output of SK mute and traffic information alarm is stopped. If traffic information identification signal is missing after trailing mute is turned off, SK mute is continuously output. If traffic information identification signal is still missing for 3 more seconds, traffic information alarm is output. During AF operation, however, previous status before starting AF operation is held. (3) When TP/SK mode is turned ON If traffic information identification signal is missing when trailing mute is turned off, output of SK mute continues. If traffic information identification signal is still missing for 3 more seconds, traffic information alarm is output. 26 µPD17006AGF-011 Symbol Functional Description (4) When CE goes high If traffic information identification signal is missing when trailing mute is turned off, output of SK mute continues. If traffic information identification signal is still missing for 3 more seconds, TP/SK traffic information alarm is output. (5) If TP/SK mode is turned off during output of SK mute or traffic information alarm Output of SK mute or traffic information alarm is stopped. This key sets PTY search mode or selects PTY. It is valid in a mode other than TP/SK mode and when an FM-band RDS station is received. When this key is pressed once, PTY mode is set. At this time, “PTY” on LCD lights, and the program type of the RDS being received at that time (e.g., “ NES ”, etc.) is displayed for 5 seconds. By pressing this key while program type is displayed (within 5 seconds), program type (1 to 16) can be selected, as follows: Program type (1) → Program type (2) → • • • • • → Program type (16) PTY (“→”: Indicates input of By pressing or SEEK UP key) PTY SEEK DOWN key while selected program type is displayed (within 5 seconds), an RDS station broadcasting the selected program type is searched for (during the search, “PTY” remains lit to indicate search for program type). If PTY , , or SEEK UP SEEK DOWN key is input for 5 seconds or more while program type is selected, PTY mode is canceled. If key other than , PTY SEEK UP , and SEEK DOWN is pressed while program type is se- lected, PTY mode is canceled, and operation of pressed key is performed. Turns ON/OFF judgment (region) of area cover code of PI code. This key is valid when initial setting diode REGEN = 1 (shorted with diode). While AF selection operation is performed and while region is judged to be ON by PI code during PI search, judgment is made by coincidence of 12 bits excluding area cover code. When region is REGION off, judgment is made by coincidence of all 16 bits of PI code including area cover code. When region is ON, “REGION” on LCD panel lights. If this key is not used (when initial setting diode REGEN = 0 (open)), all 16 bits of PI code must coincide. CD mode selection key. Each time this key is pressed CD mode and tuner/tape mode (mode before CD key is input) are alternately changed. In CD mode, MODE0 and MODE 1 pins output as follows, and CDOUT pin outputs high level: CD MODE0 MODE1 Mode 1 1 CD 27 µPD17006AGF-011 2.3 Layout of Initial Setting Diode Matrix Input Pin (Pin No.) D3 (37) D2 (38) D1 (39) D0 (40) DS4 (41) FM IF/SD AM IF/SD AMIF1 AMIF2 DS3 (42) NOCLK CTSTRT CTADJ FLASH DS2 (43) RETUNE AFSEL BEEP MESEL DS1 (44) DEV.SEL FUNC PRIDISP CLK24 DS0 (45) REGEN Output Pin (Pin No.) 28 µPD17006AGF-011 2.4 Connection of Initial Setting Diode Matrix Dn Initial setting diode 41 DS4 42 DS3 43 DS2 44 DS1 45 DS0 DSm 40 39 38 37 D0 D1 D2 D3 µ PD17006AGF–011 29 µPD17006AGF-011 2.5 Description of Initial Setting Diode Matrix The initial setting diode matrix has the following 17 types of settings.

The following RDS data are supported. • PI (Program Identification) • PS (Program Service Name) • PTY (Program Type) • AF (List of Alternative Frequencies) • EON (Enhanced Other Network) • TP (Traffic Program Identification) • TA (Traffic Announcement Identification) • CT (Clock-Time and Data) 37 µPD17006AGF-011 4.1.1 PI (Program Identification) This RDS data is used to identify broadcasting programs. After the tuning operation has been completed, the same PI code is input two times or more, so that RDS data having the same PI code is decoded. The PI counter is incremented up to eight counts. If RDS data having different PI codes are input, the PI counter is decremented, and those RDS data are not decoded, unless they are TP or TA. When the PI counter has been decremented to zero, a differing PI code is judged to be the correct PI code, the PI counter is incremented, and when the PI counter become decremented two or more, the RDS data are decoded. Fig. 4-1 shows the operation of the PI counter.

Counter – 1. 38 µPD17006AGF-011 4.1.2 PS (Program Service Name) This data is used for PS display on the LCD panel. By inputting the same PS data two times, the PS data is determined, and is displayed on the LCD panel. If the tuned station is an RDS broadcasting station when the tuning operation has been completed, PS display is performed at the point when the PS data has been determined (after about 3 seconds). Once the PS data has been input, the already input PS data is displayed even if no more PS data can be input. 4.1.3 PTY (Program Type) This data is used to identify alarms and to display program types. By inputting an alarm during RDS broadcasting station reception, the radio mode is set if the tape/CD mode is set, and the TA/DK pin (pin 25) is made low. A program type can be displayed and searched for by pressing the the description of the PTY key (for details, refer to key). PTY Program types are assigned as shown in the table below. The characters in parentheses ( ) in this table are displayed on the 14-segment portion on the LCD panel when the corresponding program type is selected.

(1) Inputting an AF list Up to 25 AF lists can be input. If more than 25 AF lists are sent, they are overwritten from the top of the list. The AF function supports both METHOD A and METHOD B. If lists are sent by METHOD B in pairs and in descending order, the following processing is performed: (a) If the area cover code of the PI code of the station currently received is ‘1’ to ‘3’, the pair in descending order is included in the list. (b) Other than above, the pair in descending order is not included in the list. 40 µPD17006AGF-011 Fig. 4-2 Inputting an AF List (1/3) AF decode Group type 0A ? N Y PI code determind ? N Y MW or LW ?

AF operations 1 and 2 are performed as follows (the condition under which AF operation 1 is performed is in FM band and when an RDS station is called): ● AF operation 1 • At CE reset • When band is changed • When preset memory is read • When tuner is selected by sound selector (except while tuner is performing seek operation) ● AF operation 2 • When electric field intensity of broadcasting currently received drops below a specific level during RDS station reception The AF operations are described below. (a) AF operation 1 AF selection is performed by the following procedure if the FM band is selected, and the station called was an RDS station, when CE reset is effected, when the band is changed, when the preset memory is read, or when the tuner is selected by the sound selector (except while the tuner is performing a seek operation). 1 The AF memories (of up to 8 stations) corresponding to the called RDS station are sorted in order of frequency. 2 The SD pin is checked starting from the highest frequency. The signal meter level at which the broadcasting station is detected is stored. 3 AF selection is performed starting from the highest signal meter level, based on the detection result in 2 . 4 If an RDS station is detected as a result of AF selection, the PI code is checked. At this time, the PI code is checked as follows: When the region mode is selected because initial setting diode REGEN = 1 and by the REGION key, coincidence of a 12-bit PI code except the area cover code of the PI code is detected; otherwise, coincidence of a 16-bit PI code is detected. When detection of coincidence of this PI code is successful, the AF operation is completed, and an RDS station is received. 5 If AF selection fails in 4 , the RDS mode is checked. A PI search operation is performed when the RDS mode is selected (for the PI search operation, refer to (3) PI search operation). When the RDS mode is not selected, the station received before AF selection is retained. If a preset memory number is being displayed at this time, it is extinguished. (b) AF operation 2 This operation is valid when the RDS mode is selected. It denotes an AF operation that is performed when receiving an RDS station and the electric field intensity of the station currently being received drops below a specific level. The start condition for AF operation 2 is as follows: 44 µPD17006AGF-011 ● AF operation 2 start condition The electric field intensity of the broadcast currently being received is input from the S-METER pin (pin 5), and the data error level is input from S-QUALITY pin (pin 6). These values are converted into digital values, which are classified as follows: A/D value of signal meter A/D value of signal quality L ≤ 48H < M ≤ 80H < H L ≤ 50H < H Caution When the signal quality is not used, fix the S-QUALITY pin (pin 6) to the low level. Depending on the combination of the classified signal meter and signal quality values, the following AF operation is performed: • When initial setting diode DEV.SEL = 0 (DEV.LEVEL is ignored) Signal Quality H L H A A M A B L B C Signal Meter • When initial setting diode DEV.SEL = 1 (DEV.LEVEL is used) Signal Quality H L H A D M D D L B C Signal Meter A : AF operation is not performed. B : AF operation 2-1 is performed. C : AF operation 2-2 is performed. D : AF operation 2-1 is performed if DEV.LEVEL (pin 74) outputs a low level and if 5 seconds or more has passed since the previous AF selection operation. (c) AF operation 2-1 • When initial setting diode AFSEL = 0 The AF of each station is changed every 5 seconds. If changing the AF fails, the original station is retained. • When initial setting diode AFSEL = 1 The AF of each station is changed at time intervals of 1 to 30 seconds generated at random. If changing the AF fails, the original station is retained. 45 µPD17006AGF-011 (d) AF operation 2-2 • When initial setting diode AFSEL = 0 AF is selected by the following procedure: 1 The AF list currently received (up to 25 stations) is sorted in order of frequency. 2 The SD pin is checked from the highest frequency, and up to eight stations of signal meter levels are stored when a station is detected. 3 Based on the result in 2 , the AF is selected starting from the station with the highest signal 4 If an RDS station is detected in the course of AF selection, the PI code is checked. meter level. At this time, the PI code is checked as follows: When the region mode is selected because the initial setting diode REGEN = 1 and the REGION key is asserted, coincidence of the 12-bit PI code excluding the area cover code of the PI code is detected; otherwise, coincidence of a 16-bit PI code is detected. The AF operation is completed when detection of coincidence of the PI code is successful, and an RDS station is received. 5 If AF selection fails in 4 , the station before AF selection was performed is retained. • When initial setting diode AFSEL = 1 The AF of each station is changed every 5 seconds. If changing the AF fails, the original station is retained. (3) PI search operation If AF selection fails when AF operation 1 has been performed, and RDS mode is set, a PI search operation is performed by the following procedure: 1 Stations are searched in the up direction in 100-kHz steps to make a pass through the band, starting from the frequency received before failure of AF selection. 2 A station is detected. If it is not an RDS station, proceed to the next step. If it is an RDS station, the PI code is checked. The PI code is checked as follows: When the region mode is selected because the initial setting diode REGEN = 1 and the REGION key is asserted, coincidence of the 12-bit PI code excluding the area cover code of the PI code is detected; otherwise, coincidence of a 16-bit PI code is detected. 3 If detection of coincidence of the PI code is successful in 2 , the AF operation is completed, and the station is received. 4 If detection of coincidence of the PI code fails in 2 , and if coincidence of the PI code is not detected after the PI search is performed, passing through the band, the frequency before the PI search is retained, and the AF operation is completed. 4.1.5 EON (Enhanced Other Network) The EON information sent as block 3 of group type 14A uses the AF list of the network of the other station and mapped FM frequency. Group type 14A and data are input by the following procedure: 46 µPD17006AGF-011 1 The PI code same as the PI code stored in block 4 of the data sent by 14A is searched from the pool memory. 2 If the PI code that coincides with the PI code stored in block 4 is found, the next frequency of block 3 of the data sent by 14A is registered in the AF list attached to that PI code. ● AF list sent by Usage Code 4 ● Mapped FM frequency sent by Usage Code 5-8 Remark The frequency is registered in 2 as follows: ● Registering an AF list sent by Usage Code 4 Up to eight stations are input to a work area. If the PI code sent by block 4 of 14A is changed, or if the receive frequency is changed, the data in the work area is updated to accept the AF list of the PI code that coincides. If a PI code that coincides is not found, the work area is updated to be a new pool memory. If there is no vacant pool memory, pool memories are overwritten starting from the oldest one that is not registered to preset memory. ● Registering an AF list sent by Usage Codes 5 to 8 (a) If a PI code that coincides already exists in pool memory The AF list in the pool memory is directly updated (refer to the figure below). PI code Usage Code 5 Usage Code 6 Usage Code 7 Usage Code 8 AF1 AF2 AF3 AF4 AF8 The storage positions corresponding to Usage Codes 5 to 8 are predetermined as shown in the above figure. AF1 takes the highest priority for AF selection. In this case, even if the AF list in a pool memory has been already registered, the pool memory is overwritten when Usage Codes 5 to 8 are input. (b) If the PI code that coincides is not in pool memory In this case, the same assumption is made as when a PI code that coincides is missing in the case of Usage Code 4. For traffic information interrupt operation of a station other than the received station, refer to 4.1.6 TP, TA. 4.1.6 TP (Traffic Program Identification), TA (Traffic Announcement Identification) These data are used to identify a traffic information station or traffic information announcement. A traffic information station is identified as follows: • When TP = 1 • When TP = 0 and TA = 1 47 µPD17006AGF-011 A traffic information announcement is identified as follows: • When broadcasting of TP = 1 It is judged that traffic information is received when TA = 1. • When TP = 0 and TA = 1 Traffic information is provided by the station whose PI is included in the group type 14B that was sent. Traffic information is selected as follows: • When TP = 1 When TA = 1, the TA/DK pin (pin 25) outputs low level. If tape/CD mode is set at this time, radio mode is set. When TA = 0, the TA/DK pin outputs high level, and the original mode is set. • When TP = 0 and TA = 1 Group type 14B is sent. When the network TA of the other station = 1, and the station given by PI indicated in block 4 is stored in a preset or pool memory, all the AF lists are checked. The station with the highest signal meter level from the stations whose PI coincide is selected and received. If no station whose PI coincides is found, a PI search operation is performed (refer to 4.1.4 (3) PI search operation). In radio mode, mute is canceled when a new broadcast is selected, and that broadcast is received. The TP and TA of that broadcast are then checked. If both TP and TA do not become 1 within 4 seconds, the original broadcast is received. In this case, selection by 14B for that PI is not made for 4 seconds. When both TP and TA become 1, the TA/DK pin outputs the low level. In the tape/CD mode, the TP and TA of the broadcast that has been selected are checked. If both TP and TA do not become 1 within 4 seconds, the original broadcast is received. If both TP and TA become 1, TA/DK pin outputs low level, and radio mode is set. In both the radio and tape/CD modes, if TP = 1 and TA = 0 later, the TA/DK pin outputs high level and the original station is received. At this time, even if 14B is received, if TA of the network of the other station = 0, the reception mode continues. If the RDS signal is no longer received after the new broadcast is selected, the original broadcast is received. ● Alarm when a traffic information station is no longer received (1) If 30 seconds have passed since a received traffic information station is no longer judged as such (except when traffic information from another station is received by EON) • In radio mode : The SK mute pin (pin 23) outputs low level, and an alarm is output (from pin 28) 3 seconds later. • In a mode other than radio mode : A Traffic information station is searched for throughout the band. (2) If the frequency is changed while ALARM (pin 28) is being output (if the newly selected broadcast is not traffic information) When the alarm stops temporarily and mute (pin 24) is canceled, SK mute is output overlapped with that mute, and alarm is output 3 seconds later. 48 µPD17006AGF-011 (3) If CE goes high and the received station is judged not to be a traffic information station, and a traffic information station is not detected 3 seconds after mute has been canceled An operation same as (1) above is performed. (4) If another mode is selected during alarm output Operation the same as in a mode other than radio mode in (1) above is performed. (5) When radio mode is set while a seek operation is being performed in a mode other than radio mode The seek up operation continues, and operation the same as in a mode other than radio mode in (1) above is performed. (6) When traffic information mode is canceled while a seek up operation is being performed in a mode other than radio mode The seek up operation continues, and the normal auto tuning operation is performed (only RDS stations are received when RDS mode is selected). ● Searching for a traffic information station When auto tuning is performed in the traffic information mode, a judgment is made 400 to 500 ms after auto tuning is temporarily stopped by SD as to whether the received station is a traffic information station, and only the traffic information station is stopped. The above traffic information operations are performed by using RDS mode even when RDS mode is not selected. 4.1.7 CT (Clock-Time and Data) This data is used to adjust the timer. The time broadcast is the Coordinated Universal Time (UTC) recommended by the CCIR. It is therefore converted to local time and used as timer data. By inputting a time announcement, the value of the internal timer of the µPD17006AGF-011 is adjusted to the value of local time. When the CTADJ switch of the initial setting diode = 1 (shorted with diode), the time can be always adjusted by inputting time announcement information. Each time the time is adjusted, the seconds are cleared to 0. Note that an adjustment can be made from time announcement information even while the timer is being adjusted by the timer being adjustment key. Whether time adjustment is made by using the time adjustment data is set by the NOCLK, CTSRT, and CTADJ switches of the initial setting diode. 49 µPD17006AGF-011 5.

S80GF-80-3B9-2 70 µPD17006AGF-011 NOTES FOR CMOS DEVICES 1 PRECAUTION AGAINST ESD FOR SEMICONDUCTORS Note: Strong electric field, when exposed to a MOS device, can cause destruction of the gate oxide and ultimately degrade the device operation. Steps must be taken to stop generation of static electricity as much as possible, and quickly dissipate it once, when it has occurred. Environmental control must be adequate. When it is dry, humidifier should be used. It is recommended to avoid using insulators that easily build static electricity. Semiconductor devices must be stored and transported in an anti-static container, static shielding bag or conductive material. All test and measurement tools including work bench and floor should be grounded. The operator should be grounded using wrist strap. Semiconductor devices must not be touched with bare hands. Similar precautions need to be taken for PW boards with semiconductor devices on it. 2 HANDLING OF UNUSED INPUT PINS FOR CMOS Note: No connection for CMOS device inputs can be cause of malfunction. If no connection is provided to the input pins, it is possible that an internal input level may be generated due to noise, etc., hence causing malfunction. CMOS device behave differently than Bipolar or NMOS devices. Input levels of CMOS devices must be fixed high or low by using a pull-up or pull-down circuitry. Each unused pin should be connected to VDD or GND with a resistor, if it is considered to have a possibility of being an output pin. All handling related to the unused pins must be judged device by device and related specifications governing the devices. 3 STATUS BEFORE INITIALIZATION OF MOS DEVICES Note: Power-on does not necessarily define initial status of MOS device. Production process of MOS does not define the initial operation status of the device. Immediately after the power source is turned ON, the devices with reset function have not yet been initialized. Hence, power-on does not guarantee out-pin levels, I/O settings or contents of registers. Device is not initialized until the reset signal is received. Reset operation must be executed immediately after power-on for devices having reset function. 71 µPD17006AGF-011 [MEMO] The application circuits and their parameters are for references only and are not intended for use in actual design-in's.
