Apparatus and methods for an interface are disclosed. In particular, an apparatus for handling hardware requests over an interface between a hardware circuit and another circuit, such as a radio frequency integrated circuit (RFIC) is disclosed. The hardware request controller apparatus utilizes a configuration memory that receives and stores data concerning memory address locations within a data memory, also within the controller. The data memory receives and stores read or write data used for reading data from and writing data to the other circuit. The controller apparatus also includes master state machine logic that receives the hardware request commands from the hardware circuit and determines which address locations are to be accessed in the data memory based on the data concerning memory locations stored in the configuration memory. An interface dependent logic, adapted to the particular interface bus, is also provided to transfer read out data from the data memory to the other circuit via an interface bus. Corresponding methods are also disclosed.
