RESET Initialization
This section describes the AC electrical specifications for the RESET initialization timing requirements of
the device. Table 7 provides the RESET initialization AC timing specifications for the MPC8560.
Table 12 provides the PLL and DLL lock times.

Notes:
1. SYSCLK is identical to the PCI_CLK signal and is the primary clock input for the device. See the MPC8560 PowerQUICC III

Notes:
1. DLL lock times are a function of the ratio between the output clock and the platform (or CCB) clock. A 2:1 ratio results in the
minimum and an 8:1 ratio results in the maximum.
2. The CCB clock is determined by the SYSCLK
× platform PLL ratio.
