Note1: The RTL8111C does not support fast 3.3V rising. The 3.3V rise time must be controlled over 1ms. If the rise time is

too short it will induce a peak voltage in PIN63, which may cause permanent damage to the switching regulator.

Note 2: If there is any action which involves consecutive ON/OFF toggling of the switching-regulator source (3.3V), the

design must makes sure the OFF state of both the switching-regulator source (3.3V) and output (1.2V) reach 0V and the

time period between the consecutive ON/OFF toggling action must be longer than 200ms.
