| | === Register Schreiben === |
| |
| Um ein Register zu schreiben muss zuerst der Opcode 'w' gesendet werden, dann die **Registeradresse** und zu letzt der neue **Wert**. | Um ein Register zu schreiben muss zuerst der **Opcode 'w' (0x77)** gesendet werden, dann die **Registeradresse** und zu Letzt der neue **Wert**. |
