Interrupt Acknowledge Cycle Timings
individual I/O (PRT, DMAC, CSI/O, ASCI) control register. The lower
vector of INT1 INT2 and internal interrupt are summarized in Table 9.
Table 9.
Figure 43 illustrates INT1, INT2, and internal interrupts timing. INT1 and
INT2 are sampled at the falling edge of the clock state prior to T2 or T1 in
the last machine cycle. If INT1 or INT2 is asserted Low at the falling
edge of clock state prior to T3 or T1 in the last machine cycle, the
interrupt request is accepted.
