Function
In most conditions, the AMIS-53050 must be returned to idle mode at
the end of a task by this command
This command is used to put the part back into idle mode. It should be used by the host to place the AMIS-53050 back into idle mode
after the AMIS-53050 has interrupted the host for reception of a packet in sniff, or to end a housekeeping cycle.
