13.3.6.6 FillMemory command
The FillMemory command fills a range of bytes in memory with a data pattern. It follows
the same rules as the WriteMemory command. The difference between FillMemory and
WriteMemory is that a data pattern is included in FillMemory command parameter, and
there is no data phase for the FillMemory command, while WriteMemory does have a
data phase.
