ABSTRACT:
Systems and methods of detecting an auto-boot mode and booting data from a serial peripheral interface to a processor without the need of a read instruction utilizing a serial peripheral interface having an auto-boot mode detector are provided. In one embodiment, a serial peripheral interface comprises a serial processing component configured to serially communicate data between the processor and at least two peripherals, and an auto-boot component operably coupled to the serial processing component, comprising an auto-boot mode detector configured to determine whether a boot mode exists based on detecting whether serial input data is received during a predetermined wait state, and configured to selectively boot data to a start address associated with the processor based on the boot mode determination.
