COMPLETION
Command Code = 0Fh
When the COMPLETION command is received, the SR176 is put in the DEACTIVED state,
and does not decode any new commands up to a Power-Off, and a new Power-On has
occurred. This allows a new SR176 to be activated by an INITIATE command, without
needing to remove the previous ones. The SR176 does not generate any response when it
executes a COMPLETION command (Figure 23).
Prior to any COMPLETION command, the SR176 must have been put in the SELECTED
mode by a SELECT command. A SR176 which was not selected does not interpret this
command.
