53 / 87 page ![]() MPC8349EA PowerQUICC II Pro Integrated Host Processor Hardware Specifications, Rev. 13 Freescale Semiconductor 53 Package and Pin Listings Figure 37 provides the AC test load for the SPI. Figure 37. SPI AC Test Load Figure 38 and Figure 39 represent the AC timings from Table 54. 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. Figure 38 shows the SPI timings in slave mode (external clock). Figure 38. SPI AC Timing in Slave Mode (External Clock) Diagram Figure 39 shows the SPI timings in master mode (internal clock). Figure 39. SPI AC Timing in Master Mode (Internal Clock) Diagram 18 Package and Pin Listings This section details package parameters, pin assignments, and dimensions. The MPC8349EA is available in a tape ball grid array (TBGA). See Section 18.1, “Package Parameters for the MPC8349EA TBGA” and Section 18.2, “Mechanical Dimensions for the MPC8349EA TBGA.
