The interrupt (INT) pins are asynchronous inputs that can be asserted at any time during a clock cycle. The
SMJ320C3x interrupts are level-sensitive, not edge-sensitive. Interrupts are detected on the falling edge of H1.
Therefore, interrupts must be set up and held to the falling edge of H1 for proper detection. The CPU and DMA
respond to detected interrupts on instruction-fetch boundaries only.
For the processor to recognize only one interrupt on a given input, an interrupt pulse must be set up and held
to:
D A minimum of one H1 falling edge
D No more than two H1 falling edges
The SMJ320C3x can accept an interrupt from the same source every two H1 clock cycles.
If the specified timings are met, the exact sequence shown in Figure 24 occurs; otherwise, an additional delay
of one clock cycle is possible.
