Weight and dimensions are approximate.About DABWith this unit you can receive and listen to Digital AudioBroadcast (DAB) programmes. DAB uses digital, not analoguesignals, resulting in near CD-quality audio with virtuallyinterference-free reception. Along with superior quality audio,DAB can also deliver additional audio channels and text. In thefuture, computer data and images are also possible.Digital radio is broadcast as groups of data called ensembles ormultiplexes. Each multiplex can contain a number of stations(services) and each station contains a primary service and cancontain secondary services as illustrated in the following diagram.Each multiplex is transmitted in a set frequency range andreceived by this unit for decoding. You can receive multiplexesbroadcast in the 174240 MHz frequency band and store theservices in each multiplex for you to access. The number ofmultiplexes you receive depend on your location. Channels usedin the UK are in the range 10A to 12D.Multiplexes and stations have labels (names) that are used toidentify them. Instead of needing to know the particular frequencyof your favourite broadcast, you can simply select the stationname. Secondary services and additional data such as text ormultiplex info are also available.DAB SIGNALMULTIPLEXPRIMARYSERVICESSECONDARYSERVICESParliamentBBC Radio 4BBCNationalDAB1123+1234+RadioFans.CN 收音机爱 好者资料库2 MICROCOMPUTER PIN FUNCTIONS31234567891011121314151617181920212223242526 2728293031323334 35363738394041 4243444546474849 50757473727170696867666564636261605958575655545352511009998979695 9493929190898887 868584838281807978 7776ST92F124V1P8.4/AIN4P8.3/AIN3P8.2/AIN2P8.1/AIN1/WKUP15P8.0/AIN0/WKUP14NCP6.5/WKUP10/INTCLKP6.4/NMIP6.3/INT3/INT5P6.2/INT2/INT4/DS2P6.1/INT6/RWP6.0/INT0/INT1/CLOCK2/8P0.7/A7/D7VDDVSSP0.6/A6/D6P0.5/A5/D5P0.3/A3/D3P0.2/A2/D2P0.1/A1/D1P0.0/A0/D0ASDSP0.4/A4/D4P1.7/A15A20/P9.6WAIT/WKUP5/P5.0WKUP6/WDOUT/P5.1TXCLK/CLKOUT/P5.4OCMPA1/P4.2VDDA21/P9.7WDIN/SOUT/P5.3DCD/WKUP8/P5.6VSSICAPB1/OCMPB1/P4.3SDA/P4.6SIN/WKUP2/P5.2RXCLK/WKUP7/P5.5CLOCK2/P4.1EXTCLK1/WKUP4/P4.4ICAPB0/P3.1ICAPA0/OCMPA0/P3.2WKUP9/RTS/P5.7ICAPA1/P4.0EXTRG/STOUT/P4.5WKUP1/SCL/P4.7OCMPB0/P3.3EXTCLK0/SS/P3.4MISO/P3.5P9.5/A19P9.4/A18P9.2/A16HW0SW1P7.7/AIN15/7/WKUP13P7.4/AIN12/WKUP3P9.3/A17P9.0/RDIRESETP7.6/AIN14/WKUP12P7.5/AIN13/WKUP11P7.1/AIN9P9.1/TDOOSCINVSSP7.3/AIN11P7.0/AIN8/CK_AFP8.7/AIN7OSCOUTVDDP7.2/AIN10AVSSAVDDP8.6/AIN6P8.5/AIN5MOSI/P3.6SCK/WKUP0/P3.7RWTOUTA0/P2.2VSS*VTESTVREGTINPB0/P2.1TOUTB0/P2.3VDDVREGA10/P1.2TINPA0/P2.0TINPB1/P2.5TOUTB1/P2.7A8/P1.0A11/P1.3A12/P1.4TINPA1/P2.4TOUTA1/P2.6A9/P1.1WKUP6NCA13/P1.5A14/P1.6* VTEST must be kept low in standard operating mode.2-1 Pin Assignment4256 bytesRegister FileRAM4 KbytesST9 CORE8/16 bitsCPUInterruptManagementMEMORY BUSRCCUExt.
