MOTOROLA
Synchronous Serial Interface (SSI)
The Transmit Shift Direction (TSHFD) bit and Transmit Bit Position(TXBIT0) in the STCR determines
how the data is transmitted. Table 30-4 displays the data bit shifting configuration and Figure 30-6 through
Figure 30-9 visually the data path for each configuration.
