The trigger command causes execution of the trigger buffer. which has been
preprogrammed with the configure trigger command "CT". The trigger buffer can also be
executed by sending the IEEE-488 group execute trigger interface message (GET).
2-60.
The following paragraphs describe how I EEE-488 commands are processed by the
Generator. Command processing is a term for how commands are executed and how
errors are handled.
2-61 .
The execution of the IEEE-488 commands depends on the selection of interface modes
with one exception: if an IEEE-488 input is buffered and the buffer becomes full,
command execution starts and no further input is accepted until there is room in the input
buffer. For more details, refer to the paragraphs on Interface Modes.
2-62.
The Generator detects two types of errors while processing IEEE-488 commands: syntax
errors and processing errors. All errors are accumulated until the error status is
interrogated or is explicitly cleared. The IEEE-488 rejected entry status is interrogated
with the "IR" command. The error status is cleared with one of the following commands:
"CE"" Clear Error Command
"CL" Clear Command
DCL or SDC Clear Interface Messages
The error status is also cleared on power-up.
