Note: You can set the ICODE 3 IC in the Quiet state and Persistent Quiet state at the same time. In this case,

the behavior is the same as for the Quiet state only until the IC enters the Power-off state. If the persistent time

has not been exceeded, the IC enters to the Persistent Quiet mode at the next power-on.
