RESTORE_DEFAULT_ALL COMMAND
Code 0x12, send byte, no data. This command downloads the factory default parameters from EEPROM into operating memory.
STORE_USER_ALL COMMAND
Code 0x15, send byte, no data. This command copies the entire contents of operating memory into EEPROM (Page 1 of the main block).

Description
Reserved.
Set the device power-up response.
0 = device powers up when power is present.
1 = device powers up only when commanded by the control pin (PSON) and the OPERATION
command.
Control how the device responds to the OPERATION command.
0 = ignore the OPERATION command.
1 = the OPERATION command must be set to 1 to enable the device (in addition to setting Bit 2).
Control how the device responds to the value of the control pin (PSON).
0 = ignore the control pin (PSON).
1 = the control pin must be asserted to enable the device (in addition to setting Bit 3).
Set the polarity of the control pin (PSON).
0 = active low.
1 = active high.
Actions to take on power-down. This bit always reads as 1 (turn off the output and stop energy
transfer to the output as fast as possible).
Description
This bit determines the device response to the OPERATION command.
0 = immediate off (no sequencing).
1 = device on.
Always reads as 0.
These bits set the output voltage margin level and are hardcoded to a value of 00.
These bits set the device response to an output OVP/UVP warning or fault after the output is
margined. These bits are hardcoded to a value of 01.
Reserved.
Description
Setting this bit disables writes to all commands except for WRITE_PROTECT.
Setting this bit disables writes to all commands except for WRITE_PROTECT, OPERATION, and
EEPROM_PAGE_ERASE.
Setting this bit disables writes to all commands except for WRITE_PROTECT, OPERATION,
EEPROM_PAGE_ERASE, ON_OFF_CONFIG, and VOUT_COMMAND.
Reserved.
