7.4.1 Initialization Mode

The LP5815 enters INITIALIZATION mode when VCC voltage ramps above the VCC_UVLO or exits from SHUTDOWN mode. The LP5815 reset all registers to default value in INITIALIZATION mode. The POR flag is set to 1 after exiting from INITIALIZATION mode to indicate the reset history.
