LP5521: Do contents of program memory remain valid after entering/exiting standby mode when setting CHIP_EN bit (0,1)?

Part Number: LP5521

The LP5521 contains a bit of memory to store LED commands used in program execution mode.  When entering low power standby mode (by setting CHIP_EN bit in the ENABLE register to 0) do the contents of this memory remain valid so that they don't need to be rewritten when exiting standby at a later time (setting CHIP_EN to 1)?  We have tested this behavior and it appears that the memory does keep its state in standby and does not get initialized when going back to normal mode, but not sure if this is guaranteed or not.  It would be helpful to know what limitations this use case might have.

Thanks

Mike
