• Manufacturer Part Number: MPC857DSL
• Description: (MPC857 / MPC862) Hardware Specifications
• Manufacturer: Motorola

Figure 10 provides 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 11 through Figure 14 provide the timing for the external bus read controlled by various GPCM
factors.
