Motorola SPI Mode
17.5.5 Motorola SPI Format with Polarity=1, Phase=0
Single and continuous transmission signal sequences for Motorola SPI format with
POLARITY=1 and PHASE=0 are shown in
Figure 17-5. Motorola SPI Frame Format (Single Transfer) with POLARITY=1 and PHASE=0
In this configuration, during idle periods:
If the SSP is enabled and there is valid data within the FIFO, the start of transmission is
signified by the SSn master signal being driven low, which causes slave data to be
immediately transferred onto the MISO line of the master, and enabling the master MOSI
output pad.

• The SSP_SCK signal is forced high.
• SSn is forced high.
• The Transmit data line MOSI is arbitrarily forced low.
• When the SSP is configured as a master, the SSP_SCK pad is an output.
• When the SSP is configured as a slave, the SSP_SCK is an input.
