Abstract
Patente de Invenção: "PROTOCOLO APERFEIçOADO PARA BARRAMENTO SERIAL ENTRE DISPOSITIVOS". Um protocolo para barramento serial entre dispositivos facilita a interconexão e comunicação entre vários dispositivos através de um barramento serial. O barramento (48) compreende um fio de clock, um fio de dados e um fio de início / parada. Uma interface mestre de barramento serial acopla um dispositivo mestre ao barramento serial. Uma interface escrava de barramento serial acopla um dispositivo escravo ao barramento serial. A interface mestre de barramento serial (180) pode compreender um iniciador de transação, um mecanismo de gravação de dados, um mecanismo de leitura de dados e um excitador de clock. O iniciador de transação inicia uma transação puxando o nível de sinal do fio de partida / parada para baixo. O mecanismo de gravação de dados controla o nível de sinal no fio de dados de acordo com os dados a serem gravados no dispositivo escravo. O mecanismo de leitura de dados lê os dados através da monitoração do nível de sinal no fio de dados. O excitador de clock controla o nível de sinal no fio de clock de acordo com um sinal de clock desejado.
