into two basic categories, maskable and non-maskable. In the MC68HC11A8 fifteen
of the interrupts can be masked using the condition code register I bit. In addition to
being maskable by the I bit in the condition code register, all of the on-chip interrupt
sources are individually maskable by local control bits.
The software interrupt (SWI instruction) is a non-maskable instruction rather than a
maskable interrupt source. The illegal opcode interrupt is a non-maskable interrupt.
The last interrupt source, external input to the XIRQ pin, is considered a non-maskable
interrupt because once enabled, it cannot be masked by software; however, it is
masked during reset and upon receipt of an interrupt at the XIRQ pin. Table 9-2, Table
9-3, and Table 9-4 provide a list of each interrupt, its vector location in memory, and
the actual condition code and control bits that mask it. A discussion of the various in-
terrupts is provided below. Figure 9-3 shows the interrupt stacking order.
