Power-on Reset (POR)
When power is turned on, power-on reset is enabled inside the LSI and its state is released after a certain power-on reset
time, tPOR. Power-on reset operation condition: Power supply rise rate tVDD must be at least 1V/ms.
Since INTOUT pin changes from “High” to “Low” at the same time as the released of power-on reset state, it is
possible to verify the tPOR externally.
During power-on reset state, Cin, Cref and Pout are unknown.
