Interrupt Pin (INT)

The interrupt pin signals any event or fault condition to the host processor. Whenever a fault or event occurs in the device, the corresponding interrupt bit is set in the INT register, and the open-drain output is pulled low. The INT pin is released (returns to Hi-Z state) and fault bits are cleared when the host reads the INT register. If a failure persists, the corresponding INT bit remains set and the INT pin is pulled low again after a maximum of 32 µs.

The MASK register masks events from generating interrupts. The MASK settings affect the INT pin only, and have no impact on the protection and monitor circuits.
