Note:
1. There may be some extra current leakage when driving signals high during this time.
2. Reset assertion timing requirements for DDR3 DRAMs may differ.
3. TRST is an asynchronous level sensitive signal. For guidance on how this requirement can be met, refer to the JTAG signal
termination guidelines in AN4232 MPC8569E PowerQUICC III Design Checklist.
4. SYSCLK is the primary clock input for the MPC8569E.
5. System/board must be designed to ensure the input requirement to the device is achieved. Proper device operation is
guaranteed for inputs meeting this requirement by design, simulation, characterization, or functional testing.
