tRES

Note:

The oscillation stable time after power ON is determined by the crystal used and the

parasitic capacitance generated by connection.

Make tRES greater than or equal to the oscillation stable time.

In the table above, the reset input pulse width indicates the minimum pulse width when

oscillation is stable after power is turned on.
