Chapter 14
Queued Serial Peripheral Interface (QSPI) Module
This chapter describes the queued serial peripheral interface (QSPI) module. Following a feature-set
overview is a description of operation including details of the QSPI’s internal RAM organization. The
chapter concludes with the programming model and a timing diagram.
14.1
The queued serial peripheral interface module provides a serial peripheral interface with queued transfer
capability. It allows users to enqueue up to 16 transfers at once, eliminating CPU intervention between
transfers. Transfer RAMs in the QSPI are indirectly accessible using address and data registers.
Functionality is very similar, but not identical, to the QSPI portion of the QSM (queued serial module)
implemented in the MC68332.
14.2
14.3
The QSPI module communicates with the integrated ColdFire CPU using internal memory mapped
registers located starting at MBAR + 0xA0. See also
diagram of the QSPI module is shown in
