PRODUCTION DATA.
In case the VDD_IN, VDD_PLL, VDD_LDO, VDD_DIG, and VDDO supplies ramp in a non-monotonic manner, TI recommends starting the device POR sequence after all core and output supplies have reached their minimum voltage tolerances (VDD ≥ 3.135 V and VDDO ≥ 1.71 V). This can be realized by delaying the PDN low-to-high transition in a manner similar to the condition detailed in Powering Up From Split-Supply Rails and shown in Figure 84.
