Abstract

SE CONECTA UN MAESTRO (DECODER) A TRAVES DE CUATRO LINEAS DE DATOS A UNO O VARIOS ESCLAVOS (CASS). CUANDO LA LINEA LISTA (14) SE ENCUENTRA EN 5V (ESCLAVO LISTO), EL MAESTRO PUEDE EMPEZAR A TRANSMITIR COMANDOS (111) Y/O DATOS SEGUN LA SIGUIENTE SECUENCIA: TRO IDENTIFICA EL BYTE DE CABECERA DE COMANDO (121) DE LOS BYTES DE DATOS A BASE DE ESTABLECER LA LINEA DE CONTROL (12) EN 0V; RESTO DEL COMANDO; ESCLAVO. LA LINEA DE CONTROL DEBE PERMANECER EN 0V DURANTE TODO EL TIEMPO QUE DURE EL BIT DE PARADA DEL BYTE DE CABECERA DEL COMANDO. ECIBIR UN NUEVO COMANDO DEL MAESTRO, ESTABLECE LA LINEA DE LISTO EN 5V; ESCLAVO; EN 0V Y PROCESA EL COMANDO; MAESTRO. CUANDO EL ESCLAVO RECIBE UN COMANDO DEL MAESTRO, NO ENVIA UN ACUSE DE RECIBO SINO QUE ENVIA DIRECTAMENTE LA RESPUESTA DEL ESCLAVO 131 CUANDO TERMINA CUALQUIER PROCESAMIENTO INTERNO. LA RESPUESTA ES ENVIADA DE MANERA ASINCRONA. EL BUS DE DATOS DE LA INVENCION SE PUEDE UTILIZAR EN CONEXION CON DIFERENTES TIPOS DE UNIDADES ESCLAVAS, EJ. UN SUBSISTEMA DEACCESO DE CONTROL PARA LA FAMILIA DE SISTEMAS D2MAC TV.
