Figure 3 shows the supply voltage sequencing and separation cautions.
Figure 3.
Supply Voltage Sequencing and Separation Cautions
Notes:
1. Numbers associated with waveform separations correspond to caution numbers listed in Table 3, “Recommended Operating
Conditions,” on page 12.
2. Refer to “Power Supply Voltage Sequencing” on page 42 for additional information.
3. Refer to Table 10 on page 25 for additional information on PLL Relock and reset signal assertion timing requirements.
4. Refer to Table 11 on page 26 for additional information on reset configuration pin setup timing requirements.
5. HRESET must transition from a logic 0 to a logic 1 in less than one SDRAM_SYNC_IN clock cycle for the device to be in the
non-reset state.
6. HRESET_CPU negates 2
17
memory clock cycles after HRESET negates.
