QSPI Bus

The QSPI bus is a full-duplex synchronous serial interface for communicating
with peripherals and other micro-controller units. The QSPI bus is a standard
Motorola bus that ESL9000 multi-unit tape library systems use as a custom
control language to communicate between master and slave tape libraries.
