Queued Serial Multi-Channel Module
15.6
The queued serial peripheral interface (QSPI) is used to communicate with external devices through a
synchronous serial bus. The QSPI is fully compatible with SPI systems found on other Freescale products,
but has enhanced capabilities. The QSPI can perform full duplex three-wire or half duplex two-wire
transfers. Several transfer rates, clocking, and interrupt-driven communication options are available.
