Interrupt
The output function of interrupt, INT, output changes according to the operating bus type and various factors.
Table 3 summarizes its behavior in Intel, Motorola 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.
