    SPI
    This section describes the DC and AC electrical specifications for the SPI of the MPC8378E.
    19.1
    SPI DC Electrical Characteristics
    This table provides the DC electrical characteristics for the device SPI.
    19.2
    SPI AC Timing Specifications
    This table provides the SPI input and output AC timing specifications.
    This figure provides the AC test load for the SPI.
    Figure 51. SPI AC Test Load
    The following two figures represent the AC timing from Table 66. Note that although the specifications generally reference the
    rising edge of the clock, these AC timing diagrams also apply when the falling edge is the active edge.

    Notes:
    1. The symbols used for timing specifications follow the pattern of t(first two letters of functional block)(signal)(state) (reference)(state) for
    inputs and t(first two letters of functional block)(reference)(state)(signal)(state) for outputs. For example, tNIKHOV symbolizes the internal
    timing (NI) for the time SPICLK clock reference (K) goes to the high state (H) until outputs (O) are invalid (X).
    2. Output specifications are measured from the 50% level of the rising edge of CLKIN to the 50% level of the signal. Timings
    are measured at the pin. The maximum SPICLK input frequency is 66.666 MHz.
    Output
    Z0 = 50

    RL = 50
