Notes:
1. Numbers associated with waveform separations correspond to caution numbers listed in Table 2.
2. See the Cautions section of Table 2 for details on this topic.
3. See Table 8 for details on PLL relock and reset signal assertion timing requirements.
4. Refer to Table 10 for additional information on reset configuration pin setup timing requirements.
5. HRST_CPU/HRST_CTRL 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 nonreset state.
6. PLL_CFG signals must be driven on reset and must be held for at least 25 clock cycles after the
negation of HRST_CTRL and HRST_CPU in order to be latched.
