STORE_USER_ALL
the RESTORE_USER_ALL command.
In general, when the STORE_USER_ALL command is sent, the existing contents of the USER store are
erased, and the contents of the working PMBus memory (volatile RAM) are written into the USER
store. There are exceptions to this behavior, as follows:
OPERATION The OPERATION command is not stored to prevent unintentional
enabling/disabling of the output.
TEST_MODE TEST_MODE is not stored to prevent unintentional operation in special
test modes.
COMP_MODEL The working memory COMP_MODEL data is only stored if the
command has been edited (as recorded by
STRAP_DISABLE ).
MANUF_CONF The manufacturer flags for password command locking are stored
independently in nonvolatile memory for security.
MANUF_PASSWD The manufacturer security password is always volatile for obvious
reasons.
USER_CONF The user flags for password command locking are stored
independently in nonvolatile memory for security.
USER_PASSWD The user security password is always volatile for obvious reasons.
DEADTIME_GCTRL This command is used to initiate a partial internal edit of the
nonvolatile “Config Page” special-purpose memory bank.
START_MEASUREMENT The Parameter Analyzer setup data is only stored in volatile memory.
CONFIG_PAGE This command is used to edit the nonvolatile “Config Page” special-
purpose memory bank.
CONFIG_STORE_NLSS This command is used to initiate a partial internal edit of the
nonvolatile “Config Page” special-purpose memory bank.
INFO_PAGE This command is used to access the nonvolatile die trim information.
NLSS_ADDR This command is stored in volatile memory only.
NLSS_DATA This command is stored in volatile memory only.
Wait at least 450ms for execution after sending the STORE_USER_ALL command before sending
additional PMBus commands.
