The processor probe controls the
target microcontroller through the
Motorola background debug mode
(BDM) port.
The BDM technology allows you
to control processor operation
even if there is no software monitor
on your target system. This feature
is particularly helpful during
the development of your target
system boot code.
The HP E3458A processor probe
only accesses the debug pins of
the target microcontroller and
affects no other signals, for a more
stable operation
