Under normal 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.
