System
Initialization
The act of powering up the board will initialize the system. The processor is
reset and dBUG is invoked.
dBUG performs the following configurations of internal resources during the
initialization. The instruction cache is invalidated and disabled. The Vector
Base Register, VBR, points to the Flash.
However, a copy of the
exception table
is made at address $00000000 in SDRAM.
To take over an exception vector, the
user places the address of the exception handler in the appropriate vector in
the vector table located at 0x00000000,
and
then
points the VBR
to
0x00000000.
The Software Watchdog
Timer is disabled, Bus Monitor enabled, and internal
timers are placed in a stop condition. Interrupt controller registers initialized
with unique interrupt level/priority pairs.
After initialization, the terminal will display:

These means are discussed in the following paragraphs.
2.2.2.1. Hard
RESET
Button.
Hard RESET is the red button located in the lower right side of the board.
Depressing this button causes all processes to terminate, resets the MCF5307
processor and board logic and restarts the dBUG firmware. Pressing the RESET
button would be the appropriate action if all else fails.
