4.4 Device States at Power-on
When the power is turned on.
(1) The MS9710C is restored to the last power-off state.
(2) The input buffer and output queue are cleared.
(3) Syntax analysis, execution control, and response parts are reset.
(4) The device is set in the OCIS (Operation Complete Command Idle State).
(5) The device is set in the OQIS (Operation Complete Query Command Idle
State).
(6) The MS9710C does not support a ∗PSC command. So the standard event
status register and standard event status enable register are cleared.
Events are recorded after being cleared.
States (2) to (5) are set except when the power is turned on. The state diagram is
shown below.
