Characters of internal interrupts - 8086

Mention the internal interrupts characteristics.

Some of the characteristics of internal interrupts are as follows:

- The type of code of an interrupt is either predefined or can be contained within the instruction itself.

- In case of INTR interrupt inputs the generation of complementary INTA bus cycles are not generated.

- No internal interrupt can be disabled in the case of such interrupts barring single step interrupts.

- Priority Wise always the internal interrupts barring single step interrupts are always given higher priority as compared to external interrupts.
