2. When power supply voltage is raised at ENBL pin = "H"
Set the ENBL pin to "L" after the power supply voltage reaches 1.8 V or higher. If the ENBL pin is set to "L" for 500
ms or longer, the oscillation start signal becomes "H", and the crystal oscillation circuit normally oscillates. After that,
if the ENBL pin is set to "H", the oscillation start signal becomes "L" within 500 ms, and the oscillation status is
maintained.
The current consumption increases to 1.7 μA typ. while the ENBL pin is set to "L".
