and waits for a command.
The user can call any of the commands supported by the firmware. A standard input routine controls the system
while the user types a line of input. Command processing begins only after the line has been entered and followed
by a carriage-return.
NOTES
1. The user memory is located at addresses $30020000-$300FFFFF, $300FFFFF is the
maximum FSRAM address of the memory installed on the board. When first learning
the system, the user should limit his/her activities to this area of the memory map.
Address range $30000000-$3001FFFF is used by dBUG.
2. If a command causes the system to access an unused address (i.e., no memory or
peripheral devices are mapped at that address), a bus trap error will occur. This results
in the terminal printing out a trap error message and the contents of all the MCF5206e
core registers. Control is returned to the dBUG monitor.

TERMINAL CONTROL CHARACTERS
The command line editor remembers the last five commands, in a history buffer, which were issued. They can be
recalled and then executed using control keys.
Several keys are used as a command line edit and control functions. It is best to be familiar with these functions
before exercising the system. These functions include:
a.
RETURN (carriage- return) - will enter the command line and causes processing to begin.
b. Delete (Backspace) key or CTRL-H - will delete the last character entered on the terminal.
c.
CTRL-D - Go down in the command history buffer, you may modify then press enter key.
d. CTRL-U - Go up in the command history buffer, you may modify then press enter key.
e.
CTRL-R - Recall and execute the last command entered, does not need the enter key to be pressed.
For characters requiring the control key (CTRL) , the CTRL should be pushed and held down and then the other
key (H,D,U or R) should be pressed.
