M68HC16 Z SERIES
USER’S MANUAL
Clock control logic allows a selection of clock polarity and a choice of two clocking pro-
tocols to accommodate most available synchronous serial peripheral devices. When
the SPI is configured as a master, software selects one of 254 different bit rates for the
serial clock.
During an SPI transfer, data is simultaneously transmitted (shifted out serially) and re-
ceived (shifted in serially). A serial clock line synchronizes shifting and sampling of the
information on the two serial data lines. A slave-select line allows individual selection
of a slave SPI device. Slave devices which are not selected do not interfere with SPI
bus activities. On a master SPI device the slave-select line can optionally be used to
indicate a multiple-master bus contention.
