When the power is turned on, reset with the NRST pulse which is equal to or
exceeds the above pulse width only after the clock oscillation is stabilized within
±
10% of error of the specified oscillator frequency.
When designing, be careful to eliminate noise from the reset line as much as
possible.

Note 14)
The permissible ripple and noise of power supply to this IC are guaranteed on
condition that the ripple frequency range is between 50 Hz and 100 Hz, the noise
frequency is at 500 kHz, and that both ripple and noise are sine wave signals as
shown below.
Pay utmost attention to these ripple signal and noise signal because they may exceed
the permissible values under the influence of the location of peripheral parts.
