NOTE
DUMP does not check for a valid address; it is a valid command only when
preceded by NOP , READ , or another DUMP command. Otherwise, an illegal
command response is returned. NOP can be used for intercommand padding
without corrupting the address pointer.
The size field is examined each time a DUMP command is processed, allowing the operand size to be
dynamically altered.
