2.2.2.2. ABORT
Button.
ABORT is the black button located next to RESET button on the right side of the
board. The abort function causes an interrupt of the present processing (a
level 7 interrupt on MCF5307) and gives control to the dBUG firmware.
This
action differs from RESET in that no processor register
or memory
contents are
changed, the processor and peripherals are not reset, and dBUG
is not
restarted. Also, in response to depressing the ABORT button, the contents of
the MCF5307 core internal registers are displayed.
The abort function is most appropriate when software is being debugged.
The
user can interrupt the processor without destroying the present state of the
system.
This is accomplished by forcing a non-maskable interrupt that
will call
a ROM
monitor routine to preserve the current state of the registers to
shadow
register in the monitor for display to the user.
The user will be
returned to the ROM monitor prompt after exception handling.
2.2.2.3. Software
Reset
Command.
dBUG does have a command
that causes the dBUG to restart as if a hardware
reset was invoked.
The command is "RESET".
2.2.2.4. USER
Program.
The user can return control of the system to the firmware by recalling dBUG
via
his/her program.
Instructions can be inserted into the user program to call
dBUG via the TRAP 15 handler.
2.2.3.
