Measurement Computing Micro 488/EX rev.2.1 - Manual (Page 56)

Section 4 General Programming
4.14
PERIPHERAL This event occurs when the Micro488/EX is force from the
Controller Active State (*SC•CA) to the Peripheral State
(*SC•*CA) by receipt of IFC from the System Controller.
This can be useful in detecting receipt of IFC when in the
*SC•CA state. This event is edge sensitive.
CONTROLLER This event occurs when the Micro488/EX receives control
of the bus and transitions from the Peripheral State
(*SC•*CA) to the Controller Active State (*SC•CA). This
occurs when the Take Control interface message is
received by the Micro488/EX. This event is edge
sensitive.
TRIGGER This event occurs when the Micro488/EX, as a Peripheral
(*CA), receives a Group Execute Trigger (GET) command
from the Active Controller. This event is edge sensitive.
When the MACRO is executed, the internal status, as read
by the STATUS 1 command, is cleared.
CLEAR This event occurs when the Micro488/EX, as a Peripheral
(*CA), receives a Device Clear (DCL) or a Selected
Device Clear (SDC) command from the Active Controller.
This event is edge sensitive. When the MACRO is executed,
the internal status, as read by the STATUS 1 command, is
cleared.
TALK This event occurs when the Micro488/EX, as a Peripheral
(*CA), detects its My Talk Address (MTA) command
from the Active Controller. It indicates that the controller
has requested information from the Micro488/EX. This
event is edge sensitive.
LISTEN This event occurs when the Micro488/EX, as a Peripheral
(*CA), detects its My Listen Address (MLA) command
from the Active Controller. It indicates that the controller
has information it wants to send to the Micro488/EX. This
event is edge sensitive.
