VDDC Levels
The V_DDC supply has one monitor: the Power-OK (POK). The POK monitor is used to keep the
digital circuitry in reset until the V_DDC power supply is at an acceptable operational level. The digital
Power-On Reset (Digital POR) is only released when the Power-On Reset has deasserted and
all of the Power-OK monitors for each of the supplies indicate that power levels are in operational
ranges. Figure 23-6 on page 1332 shows the relationship between POK and V_DDC.
