INTEL 186 EB/EC EVALUATION BOARD USER’S MANUAL

default base and then a series of lines showing the contents of the selected ports. The next line starts with a hexadecimal display of the address of the next PORT variable to be displayed, followed by the display of up to 16 PORT variables in the default base. A new line starts whenever 16 ports have been displayed on the line. The command terminates when all of the PORT variables in the selected range have been displayed. During lengthy displays, you can stop the output to the console by pressing the space bar. You can resume the display by pressing the space bar a second time. You terminate the command by entering a carriage return.

PORT port_address TO port_address = byte_value

This form is used to initialize a set of ports to byte_value. Note that this command takes a little over a millisecond (at 9600 baud) for each PORT loaded. You can terminate this command by entering a carriage return, but terminating the command leaves only part of the memory region initialized.

5.4.8WPORT Commands

There are four basic forms for the WPORT commands:

WPORT wport_address

WPORT wport_address = word_value

WPORT wport_address TO wport_address

WPORT wport_address TO wport_address = word_value

All of these commands can be used whether or not the user’s program is running.

WPORT wport_address

This form is used to examine and possibly change one or more sequential WPORT variables. When this command is invoked, iECM-86 displays the wport_address in hexadecimal notation and the value of the WPORT in the default base, then waits for an input from you. You can respond with a carriage return, an ESC, or a numeric value. A carriage return terminates the command. An ESC results in the display of the next sequential WPORT variable. If a numeric value is entered, the WPORT variable is set to this value and the iECM-86 again waits for input. At this point, you can respond only with an ESC or carriage return. As before, the ESC displays the next sequential WPORT and the carriage return terminates the command.
