Stay Quiet

On receiving the Stay Quiet command, the LRI1K enters the Quiet state and does NOT

send back a response. There is NO response to the Stay Quiet command even if an error

occurs.

When in the Quiet state:

●

the LRI1K does not process any request if the Inventory_flag is set,

●

the LRI1K processes any Addressed request

The LRI1K exits the Quiet state when:

●

it is reset (power off),

●

receiving a Select request. It then goes to the Selected state,

●

receiving a Reset to Ready request. It then goes to the Ready state.

The Stay Quiet command must always be executed in the Addressed mode (Select_flag is

reset to 0 and Address_flag is set to 1).
