The output function of interrupt, INT, output changes according to the operating bus type and various factors.
Table 3
summarizes its behavior in Intel and PC mode of operation. Multiple interrupts can be wire-OR’ed. This
is accomplished by setting MCR bit-5 to a logic 1 and connecting a 1K
to 10K
resistor between this pin and
ground to provide an acceptable logic 0 level.
