Under nor,al conditions, the signals –SBHE, LA17 – LA23, –MEMR and MEMW
are operated as outputs (sending from CPU). Only CPU modules that are suitable
for use as a master CPU for system bus access send and receive these signals. A
minus sign, ”–”, in front of the signal name shows that the signal is LOW active.
