SRI4K commands
8.5
32/49
COMPLETION() command
Command Code = 0Fh
On receiving the COMPLETION() command, a SRI4K in SELECTED state switches to
DEACTIVATED state and stops decoding any new commands. The SRI4K is then locked in
this state until a complete reset (tag out of the field range). A new SRI4K 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 SRI4K devices not in SELECTED state ignore the COMPLETION() command.
