Instruction in interrupt
routine
(b)
Interrupt response time
(a) The period from the occurrence of an interrupt to the completion of the instruction under execution.
(b) The time required for executing the interrupt sequence.
Figure 1.9.5 Interrupt response time
Time (a) varies with each instruction being executed. The DIVX instruction requires a maximum time that
consists of 29* cycles.
Time (b) is shown in table 1.9.6.
* It is when the divisor is immediate or register. When the divisor is memory, the following value is
added.
• Normal addressing
:2+X
• Index addressing
:3+X
• Indirect addressing
: 5 + X + 2Y
• Indirect index addressing : 5 + X + 2Y
X is number of wait of the divisor area. Y is number of wait of the indirect address stored area.
When X and Y are in odd address or in 8 bits bus area, double the value of X and Y.
