  • SPI addressing beyond 24-bits
    Patent number: 7849229
    Abstract: A system and/or methodology that facilitates serial peripheral interface (SPI) addressing beyond 24 bits, by portioning a conventional SPI command byte into a plurality of nibbles. A new set of commands are mapped to the first nibble, and selected from the set of unused binary values under the conventional SPI command protocol. A number of address bytes required to access the storage location for the command are mapped on a second nibble, and a user and/or system definable number of dummy bytes to be sent after the command are mapped on a third nibble.
