• Manufacturer Part Number: MPC866
• Description: (MPC859 / MPC866) Hardware Specifications
• Manufacturer: Freescale Semiconductor

Figure 11 shows the timing for the input data controlled by the UPM for data beats where DLT3 = 1 in the
UPM RAM words. (This is only the case where data is latched on the falling edge of CLKOUT.)
Figure 12 through Figure 15 show the timing for the external bus read controlled by various GPCM factors.
