Figure 3.   Example SRAM data block, show both states “Active” and “Flushing”

The image above shows an example active SRAM block first near full, then “flushing” momentarily to flash—an operation that lasts only a second or two. Another SRAM block becomes active when this happens, and it is used until it fills and needs to flush to flash.

Above the bar graph of each block, its Status is described, typically as either: “Active”, “Idle”, or sometimes “Flushing”, with other states “Purging”, “Awaiting Idle”, “Flush Queued”, “Defragmenting”, “Reserved”, “Fail”, and “Unknown”.

Below the bar graph of each block, numerical amounts display, in bytes, for its total Capacity, currently Used space, calculated Overhead Space, and available Free Space.
