Notes:
1) After PWROK assertion, the VID signals change from the Metal Mask VID to the value programmed during
device manufacturing.
2) MaxVID is reported in MSRC001_0071 (COFVID_STATUS).
Refer to the thermal/power tables under the
appropriate SOPN section for this OPN-

Notes:
1) The voltage set-point must be contained within the DC specification in order to ensure proper operation.
Voltage ripple and transient events outside the DC specification must remain within the AC specification at all.
times. Transients above dc max must return to within the DC specification within 30 μS and must stay under a
triangle described by the AC limit at one end and the DC limit at the other, as shown in
Figure 8 on page 93.
