Definition: The SNAPSHOT command is a 32-byte read-back of parametric and status values. It allows monitoring and status data to be

stored to flash either during a fault condition or via a system-defined time using the SNAPSHOT_CONTROL command. In case of a fault,

last updated values are stored to the flash memory. Use SNAPSHOT_CONTROL command to read stored values.

BLANK_PARAMS (EBh)

Definition: Returns a 16-byte string which indicates which parameter values were either retrieved by the last RESTORE operation or

have been written since that time. Reading BLANK_PARAMS immediately after a restore operation allows the user to determine which

parameters are stored in that store. Index to read BLANK_PARAM is provided in âPMBus Command Summaryâ on page 27. One

indicates the parameter is not present in the store and has not been written since the RESTORE operation.
