| Der FPGA enthält ein paar Register, die über den SPI Bus vom Microcontroller geschrieben/gelesen werden können. Mithilfe dieser Register werden alle Blöcke, die implementiert wurden, konfiguriert. | Der FPGA enthält ein paar Register, die über den SPI Bus von einem Microcontroller geschrieben/gelesen werden können.

| ==== Schreiben / Lesen ==== | ==== SPI Kommunikation ==== |
| Um ein Register zu schreiben muss zuerst der **Opcode 'w'** gesendet werden, dann die **Registeradresse** und zu Letzt der neue **Wert**. | |
