Interrupts
The Z86L82X features six different interrupts. The interrupts are maskable and
prioritized, as shown in Figure 43. The six sources are divided as follows: three
sources are claimed by Port 3 lines P33–P31, two by the counter/timers, and one
by LVD (see Table 21). The Interrupt Mask Register, globally or individually,
enables or disables the six interrupt requests.
