Hi José,
i try it in your language (thx to google :)
Eu signifiquei a unidade, que fornece o processador central com o pulso
de disparo (normalmente uma unidade preta). Este componente é necessário
de modo que o processador trabalhe. É possível, isso que é soldado
completamente perto no processador central.
I hope you can understand what i mean :)
Greetings
Stef
