Resets and Interrupts
MOTOROLA
Resets and Interrupts
triggered only or both positive-edge and high-level triggered. The
level-sensitive triggering option allows multiple external interrupt
sources to be wire-ORed to an external interrupt pin. An external
interrupt request, shown in Figure 5-5, is latched as long as any source
is holding an external interrupt pin low.
