Multiple MVME230x boards may be installed in a single VME
chassis. Each must have a unique Universe address, selected by
setting jumpers on its J17 header, as described in Preparing the
MVME230x. In general, hardware multiprocessor features are
supported.
Other MPUs on the VMEbus can interrupt, disable, communicate
with, and determine the operational status of the processor(s). One
register of the Universe set includes four bits that function as
location monitors to allow one MVME230x processor to broadcast
a signal to any other MVME230x processors. All eight registers are
accessible from any local processor as well as from the VMEbus.
