INTEL 186 EB/EC EVALUATION BOARD USER’S MANUAL

NOTE

Most monitor programs similar to iECM-86 display a message on the console when a break occurs (e.g., “Program break at 1234H”). This is not done in iECM-86 because the system supports concurrent interrogation of the target on which the user's code is running; it is possible that the break will occur while you are in the middle of displaying or modifying the state of the target. Any special break message would have to interrupt the execution of the command. Because of this, the iECM-86 does not output a special break message. You have two ways to find out that a break occurred:

•The prompt changes from a greater-than sign (>) to an asterisk (*).

•The status of the processor shown in the “control panel” at the top of the console screen changes from “running” to “stopped.”

Commands which set the breakpoint array are:

BR

BR [ bp_number ]

BR [ bp_number ] = code_addr

The square brackets in the latter two commands are part of the command syntax and must be entered by the user; the angle brackets are part of the “meta” language used to describe the syntax. Breakpoints can be displayed while your code is running, but they cannot be modified.

NOTE

BR[0] and BR[1] can also be set by the GO command by using the TILL clause; all breakpoints are cleared by the GO command if the FOREVER clause is used.

BR

This command displays all of the active breakpoints (i.e., those not

 

set to zero). You are also informed if no breakpoints are active.

BR [ bp_number]

This command displays the setting of the selected breakpoint and

 

waits for input from you. If you enter a carriage return, the command

 

terminates. If you enter an ESC, the next sequential breakpoint is

 

displayed. If you enter a numeric value, the selected breakpoint is

 

loaded with the value and the iECM-86 again waits for input. At this

 

point, you can enter either a carriage return or an ESC. As before, the

 

ESC causes the iECM-86 to display the next breakpoint and the

 

carriage return terminates the command. This command wraps

 

around from the last breakpoint (15t) to the first breakpoint (0).

BR [bp_number] = code_addr

This command sets the specific breakpoint specified

 

 

by bp_number to the value code_addr.
