PRODUCTION DATA.
The VDDC supply has one monitor, the Power-OK (POK). The POK monitor is used to keep the digital circuitry in reset until the VDDC power supply reaches an acceptable operational level. The digital reset is only released when the power-on reset has deasserted and the POK monitor for each supply indicates that power levels are in operational ranges. Figure 5-4 shows the relationship between POK and VDDC.
