PRODUCTION DATA.
The power rails VCCA, VCCIO, VCCD_PLL, and VCC_INT can come up in any order. All the rails have to rise monotonically to the recommended voltage levels within tRAMP time (see Figure 16). A power on reset (POR) is internally generated as soon as all the power rails are within the recommended levels.
