4.1.2 Operating Conditions
When assigning supply sources, the following requirements must be observed:
• VREGVDD must be the highest voltage in the system
• VREGVDD = AVDD
• DVDD ≤ AVDD
• IOVDD ≤ AVDD
• RFVDD ≤ AVDD
• PAVDD ≤ AVDD

Note:
1. VREGVDD must be tied to AVDD. Both VREGVDD and AVDD minimum voltages must be satisfied for the part to operate.
2. The minimum voltage required in bypass mode is calculated using R_BYP from the DCDC specification table. Requirements for
other loads can be calculated as V_{DVDD_min}+I_LOAD * R_{BYP_max}
