The DUMP command does not check for a valid address in the tem-
porary register — DUMP is a valid command only when preceded by
another DUMP or by a READ command. Otherwise, the results are
undefined. The NOP command can be used for inter-command pad-
ding without corrupting the address pointer.
The size field is examined each time a DUMP command is given, allowing the operand
size to be altered dynamically.

the READ command: $0xxxx for success, $10001 for bus or address errors.
