Regarding the backup of nvSRAM, is it possible to control it with SW other than when the power is turned off?

He MAO,

There are two methods to manually STORE or RACALL for nvSRAM.
1. hardware method
    a. Drive the nHSB pin Low to STORE the contents of the SRAM to non-volatile memory.
    b. REACALL the contents of the nonvolatile memory to the SRAM on power-up.
2. Software method
    a. STORE/RECALL can be performed by reading data from a specific address in sequence.

Refer to the "Device Operation" section of the datasheet for details.

Regards,

Shimamura
