Section 5 Interrupt Controller
5.6.4
Table 5.7 shows interrupt response times—the intervals between generation of an interrupt request
and execution of the first instruction in the interrupt handling routine. The execution status
symbols used in table 5.7 are explained in table 5.8.
Table 5.7
Notes: 1. Two states in case of internal interrupt.
