SOFTWARE DESIGN DESCRIPTION
3.1
OPERATING PROCEDURES
A resident terminal program permits the user to interact with the MC145572EVK. The commands provide
the following functions:
a. Activation with or without loop-backs.
b. Modications to and displays of registers.
c. Modications to and status of eoc functions.
d. Deactivation options.
3.1.1
Power On Reset and Terminal Prompt
Applying power to the MC145572EVK causes a power on reset to occur which invokes the resident terminal
program.
1. When the terminal is connected to the NT1 side EIA-232 connector (J16), the terminal displays
the following:
MC145572EVK EVALUATION CARD Vx.x
MC68HC705C8 VERSION
NTLT>
where: x.x is the software revision number.
3.1.2
Command Line Interface
After initialization or return of control to the monitor, the terminal displays the NTLT> prompt. If an invalid
command is entered, ! INVALID COMMAND ! is displayed on the terminal. This error message is
accompanied by a BELL. All erroneous commands are accompanied by an appropriate error message
accompanied by a BELL.
The MC145572EVK waits for a command line input from the terminal. All commands can be entered as
lower or upper case. When a valid command has been entered, the command is executed or a menu is
brought up. All menus prompt the user for appropriate inputs to select a function or to quit the menu.
