11 / 106 page  Data Sheet S15082EJ4V0DS 11 µPD61051, 61052 1.6 Stream Output Interface This interface outputs MPEG TS/PS stream. When in master mode (MPEG2-TS output with using valid signal), data output is possible to select 8bits parallel data or serial data mode. In serial mode, data output from OS0. Active polarity of OSVLD is selected by the port setup register. Active polarity of OSCLK/OSSTB and OSSYNC are selected by firmware. These are unsettled after the turning on. Name IO Pin Number Function Active Polarity OSREQ I 70 Stream data request in slave mode L OSCLK/OSSTB O 66 Stream data strobe After reset, default is active high edge. OSCLK/OSSTB O 66 Stream data clock After reset, default is OSSTB. OSSYNC O 67 Stream data synchronization After reset, default is active high. OSVLD/OSRDY O 68 Stream data valid After reset, default is OSRDY. OSVLD/OSRDY O 68 Stream data ready prepared After reset, default is active low. OS7 to OS0/ FA13 to FA6 O 65 to 63, 61, 59 to 56 Stream data output Remark In this table, means of reset are hardware reset by the RESET pin and ALL RESET of the reset register. 1.7 SDRAM Interface Name IO Pin Number Function Active Polarity MA13 to MA0 O 104, 103, 115, 102, 114, 113, 111, 109, 108, 106, 101, 99, 97, 95 Address of row/column MD31 to MD0 IO 93 to 89, 87, 85, 83, 72, 75 to 81, 149, 147 to 143, 141, 139, 127, 129, 131 to 134, 136, 138 Data (Built-in 50 k Ω pull up resistor) MCLK O 118 Clock ↑ MCKE O 116 Clock enable H MCS O 120 Chip selection L MRAS O 121 Row address strobe L MCAS O 123 Column address strobe L MWE O 125 Write enable L MDQM O 126 Data input/output mask enable L |
