The RESTORE_USER_ALL command restores all of the storable register settings from EEPROM memory to those registers which are unprotected according to current setting of WRITE_PROTECT. Issuing STORE_USER_ALL also causes the device to be unresponsive through PMBus for a period of approximately 100 ms.
This command shres the same harware implementation as RESTORE_DEFAULT_ALL.
Do not use this command while the device is actively switching, this causes the device to stop switching and the output voltage to fall during the restore event. Depending on loading conditions, the output voltage could reach an undervoltage level and trigger an undervoltage fault response if programmed to do so. The command can be used while the device is switching, but this usage is not recommended as it results in a restart that could disrupt power sequencing requirements in more complex systems. TI strongly recommends stopping the device before issuing this command.
