MMDS Commands

CT *

Clears all triggers.

This command clears both triggers of a range definition, even though just one of the triggers is a parameter value.

Example:

If triggers C and D define a range, CT C clears both the triggers.

ST

A.1.2.4 Short Description

set trigger.

A.1.2.5 Syntax

ST [id [[!] [(address address range ,) [(data data range ,) [(clips ,) [LIR= (X H L)]]]] [;R ;W;RW] [;D] ]]

A.1.2.6 Description

The ST command defines one of the four bus analyzer triggers. If this command includes only a value or id parameter value, the command interpreter opens the Trigger Specification dialog box. You can use the dialog box to set the trigger value interactively.

id: The id of the analyzer trigger: A, B, C, or D.

!: The inversion operator for the entire trigger definition. Specifying !, as well as an address, data value, and clip value, means that the trigger occurs when the address is not the specified value, or the data value is not the specified value, or the clip value s not the specified value. Specifying ! with a range is specification means that the trigger occurs at values outside the range, and at the lowest value of the range.

address: Address that is to trip the trigger, specified with an address constant:

address[:mask]

If you include a mask value, the system comparison involves only the address bits that correspond to ones (1s) of the mask.
