voltage falls below a certain level.

The oscillation stabilization time refers to the time interval that is required for the oscillation to get stabilized
after the instruction for starting the subclock oscillator circuit is executed plus the time interval that is required
for the oscillation to get stabilized after the HOLD mode is released (see Figure 4).
Note : The traces to and from the components that are involved in oscillation should be kept as short as possible
as the oscillation characteristics are affected by their trace pattern.

• The POR function generates a reset only when power is turned on starting at the VSS level.
• No stable reset will be generated if power is turned on again when the power level does not go
down to the VSS level as shown in (a). If such a case is anticipated, use the LVD function
together with the POR function or implement an external reset circuit.
• A reset is generated only when the power level goes down to the VSS level as shown in (b) and
power is turned on again after this condition continues for 100μs or longer.
