Note 1

Polarity at the source of the flag: P = active-high, N = active-low.

General rule is: normal system state is high, and abnormal system state is low (for example,

PG = high means power-good, TEMP_CRIT = low when TEMP critical state).

Note 2

Interrupt outputs the status as is. I2C write is not required for interrupt clear.

Note 3

OTP load value defined by CONF pin setting if CONF_EN = 1.
