simultaneously.
An indefinite period of time appears, from the time that power is turned on to the time that
both of the 1.2-V power supply and the 3.3-V power supply rise to the Min. voltage (1.1 V
for 1.2-V power supply and 3.0 V for 3.3-V power supply), or from the time that either of the
1.2-V power supply or the 3.3-V power supply is turned off and passes the Min. voltage (1.1
V for 1.2-V power supply and 3.0 V for 3.3-V power supply) to the time that both of the 1.2-
V power supply and the 3.3-V power supply fall to GND.
During these periods, states of output pins and in-out pins and internal states become
undefined. So it should be as short as possible. Also design the system so that these
undefined states do not cause an overall malfunction.
