Notes: Unused input pins must be pulled up or pulled down with a resistance of 4.7 kΩ to 10 kΩ.
* The following power-on/power-off order is recommended when applying a 5 V voltage
to power supply voltage pin PVCC. When PVCC is also used with the same 3 V voltage
as VCC, etc., simultaneous powering on and off is recommended for all power supplies.
1. Powering on
(1) Turn on the 5 V power (PVCC) first, then the 3 V power (VCC, PLLVCC, AVCC).
(2) Pin states are undefined while only 5 V power (PVCC) is on, as reset input is invalid.
2. Powering off
(1) Power off in the reverse order to powering on: Turn off the 3 V power first, then the
5 V power.
(2) Pin states are undefined while only 5 V power is being supplied.
3. Power-on/off interval
To minimize the length of time during which pin states are undefined, the power-on/off
interval should be kept as short as possible. Also, the system design should ensure that
erroneous system operation will not result from pin states becoming undefined.
