9.3 Queued Serial Peripheral Interface
M68HC16 Z SERIES
USER’S MANUAL
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 sys-
tems found on other Freescale products, but has enhanced capabilities. The QSPI can
perform full duplex three-wire or half duplex two-wire transfers. A variety of transfer
rates, clocking, and interrupt-driven communication options is available.
