23.5.6 Motorola
23.5.6.1 SPO Clock Polarity
23.5.6.2 SPH Clock Phase
23.5.7 Motorola SPI Format with SPO=0, SPH=0
SFRMOUT /
SCLKOUT /
The Motorola SPI interface is a four-wire interface where the SFRMOUT signal behaves as a
slave select. The main feature of the Motorola SPI format is that the inactive state and phase
of the SCLKOUT signal are programmable through the SPO and SPH bits within the control
register,
When the SPO clock polarity control bit is LOW, it produces a steady state low value on the
SCLKOUT pin. If the SPO clock polarity control bit is HIGH, a steady state high value is
placed on the SCLKOUT pin when data is not being transferred.
The SPH control bit selects the clock edge that captures data and allows it to change state. It
has the most impact on the first bit transmitted by either allowing or not allowing a clock
transition before the first data capture edge.
When the SPH phase control bit is LOW, data is captured on the first clock edge transition. If
the SPH clock phase control bit is HIGH, data is captured on the second clock edge
transition.
Single and continuous transmission signal sequences for Motorola SPI format with SPO=0,
SPH=0 are shown in
