Section 43 Electrical Characteristics
43.2
43.2.1
There are no restrictions on the power-on order. After a single power supply is turned on, all other
power supplies should be turned on within 10 ms. It is recommended that this time period is as
short as possible. The system should be designed so that a system malfunction is not caused by the
undefined states of pins and internal circuits.
The internal circuit states are undefined until a low level is input to the RESETP pin after voltage
is applied to all power supplies. While the internal circuit states are undefined, the state of each
pin is also undefined. Accordingly, the system should be designed so that a system malfunction is
not caused by such undefined state.
43.2.2
There are no restrictions on the power-off order. After a single power supply is turned off, all
other power supplies should be turned off within 10 ms. It is recommended that this time period is
as short as possible.
The system should be designed so that a system malfunction is not caused by the undefined states
of pins and internal circuits.
