Figure 11.6 shows an interrupt response time. Interrupt response time is the period between an interrupt
generation and the execution of the first instruction in an interrupt routine. Interrupt response time in-
cludes the period between an interrupt request generation and the completed execution of an instruction
((a) on Figure 11.6) and the period required to perform an interrupt sequence ((b) on Figure 11.6).
Time (a) varies depending on an instruction being executed. The DIVX instruction requires the longest
time (a); 42 cycles when an immediate value or register is set as the divisor.
When the divisor is a value in the memory, the following value is added.
X is the number of wait states for a divisor space. Y is the number of wait states for the space that stores
indirect addresses. If X and Y are in an odd address or in 8-bit bus space, the X and Y value must be
doubled.
Table 11.4 lists time (b) shown Figure 11.6.
