The table shown above is recommended values, so they represent guidelines rather than
strict requirements. Either 3.3 V- or 1.25 V- power supply can be turned on or off first,
though, an undefined period appears until the power that is turned on later rises to the Min.
voltage or after the power that is turned off earlier passes the Min. voltage to 0 V. During
these periods, pin or internal states become undefined. Design the system so that these
undefined states do not cause an overall malfunction.
