In a typical implementation, the power supply should target the NOM voltage.
The voltage at the device ball should never be below the MIN voltage or above the MAX voltage for any amount of time. This requirement includes dynamic voltage events such as AC ripple, voltage transients, voltage dips, etc.
The DC voltage at the device ball should never be above the MAX DC voltage to avoid impact on device reliability and lifetime POH (Power-On Hours). The MAX DC voltage is defined as the highest allowed DC regulated voltage, without transients, seen at the ball.
For all OPPs, AVS must be enabled to avoid impact on device reliability, lifetime POH (Power-On Hours), and device power.
The AVS voltages are device-dependent, voltage domain-dependent, and OPP-dependent. They must be read from the STD_FUSE_OPP. For information about STD_FUSE_OPP Registers address, please refer to Control Module section of the Device TRM. The power supply should be adjustable over the following ranges for each required OPP:
- OPP_LOW for MPU: 0.85 V - 1.15 V
- OPP_NOM for MPU: 0.85 V - 1.15 V
- OPP_NOM for CORE and Others: 0.85 V - 1.15 V
- OPP_OD: 0.885 V - 1.15 V
- OPP_HIGH: 0.95 V - 1.25 V
- OPP_PLUS: 0.95 V - 1.25 V
The AVS voltages will be within the above specified ranges.
The power supply must be programmed with the AVS voltages for the MPU and the CORE voltage domain, either just after the ROM boot or at the earliest possible time in the secondary boot loader before there is significant activity seen on these domains.

Table 5-4 describes the standard processor clocks speed characteristics vs OPP of the device.
