The eSPI Master/Slave Controller adheres to the Enhanced Serial Peripheral Interface (eSPI) specification, facilitating communication either as a master or slave device within the eSPI protocol. It provides support for both the transaction and link layers of the eSPI bus, making it suitable for integration with a range of AMBA-compliant interconnect systems like AXI or AHB. This controller is particularly adept at bridging communications between various SPI devices and internal processing units, ensuring robust data exchange in complex system architectures.
