LVD Pulse
6.8. POR & LVD : Power-On Reset
On-chip power-on reset is a logical OR of
RC-POR and LVD-POR
RC-POR operates when the rising time of
power (V
On-chip LVD
After POR pulse is off, the internal clock
stabilization counter starts to run, which
lengthens power-on reset about 4.5 ms.

Provides power-on reset when the rising time
of power is relatively long.
Power-on reset voltage is 1.7 V.
Provides power-fail reset when the power
goes down below 1.6 V.
