Freescale Semiconductor 28-31
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.
