Hi Kuramochi,

If using an oscillator, the clock must be present at power-up.

If using 2 supply mode, there is no supply sequence.

If using 3 supply mode, please reference the figure 31 and table 107 in the datasheet.

Ross-san,

Thank you for your answer.

>If using an oscillator, the clock must be present at power-up.

Does it mean that we need to input clock before power up?

Does reset timing have no restriction?
