11.3 Queued Serial Peripheral Interface
MC68HC16Y3/916Y3
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 Motorola 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.
Figure 11-2 displays a block diagram of the QSPI.

1. PQS2 is a digital I/O pin unless the SPI is enabled (SPE set in SPCR1), in which case it
2. PQS7 is a digital I/O pin unless the SCI transmitter is enabled (TE set in SCCR1), in
RXD
becomes the QSPI serial clock SCK.
which case it becomes the SCI serial data output TXD.
