Method and System for a Serial Peripheral Interface
摘要:
An integrated circuit includes a serial peripheral interface memory device. In an embodiment, the memory device includes a clock signal, a plurality of pins, and a configuration register. In an embodiment, the configuration register includes a wait cycle count. The method includes transmitting a read address to the memory device using a first input/output pin and a second input/output pin concurrently. In an embodiment, the read address includes at least a first address bit and a second address bit, the first address bit being transmitted using the first input/output pin, and the second address bit being transmitted using the second input/output pin. The method includes accessing the memory device for data associated with the address and waiting a predetermined number clock cycles associated with the wait cycle count. The method includes transferring the data from the memory device using the first input/output pin and the second input/output pin concurrently.
