SRT512 commands
8.5

COMPLETION() command
Command Code = 0Fh
On receiving the COMPLETION() command, a SRT512 in SELECTED state switches to
DEACTIVATED state and stops decoding any new commands. The SRT512 is then locked
in this state until a complete reset (tag out of the field range). A new SRT512 can thus be
accessed through a SELECT() command without having to remove the previous one from
the field. The COMPLETION() command does not generate a response.
All SRT512 devices not in SELECTED state ignore the COMPLETION() command.
