Notes:
1. Dotted waveforms correspond to optional supply values for a specified power supply. See Table 2.
2. The recommended maximum ramp up time for power supplies is 20 milliseconds.
3. Refer to Section 5, “RESET Initialization” for additional information on PLL relock and reset signal
assertion timing requirements.
4. Refer to Table 11 for additional information on reset configuration pin setup timing requirements. In
addition see Figure 68 regarding HRESET and JTAG connection details including TRST.
5. e600 PLL relock time is 100 microseconds maximum plus 255 MPX_clk cycles.
6. Stable PLL configuration signals are required as stable SYSCLK is applied. All other POR configuration
inputs are required 4 SYSCLK cycles before HRESET negation and are valid at least 2 SYSCLK cycles
after HRESET has negated (hold requirement). See Section 5, “RESET Initialization” for more
information on setup and hold time of reset configuration signals.
7. VDD_PLAT, AVDD_PLAT must strictly reach 90% of their recommended voltage before the rail for
D
n_GVDD, and Dn_MVREF reaches 10% of their recommended voltage.
8. SYSCLK must be driven only AFTER the power for the various power supplies is stable.
9. In device sleep mode, the reset configuration signals for DRAM types (TSEC2_TXD[4],TSEC2_TX_ER)
must be valid BEFORE HRESET is asserted.
