What is the disadvantage of a level triggered pulse?
A. a constant pulse is to be maintained for a greater span of time
B. difficult to analyse its effects
C. it is difficult to produce
D. another interrupt may be caused, if the signal is still low before the completion of the last instruction
Answer:A

Explanation: In a level triggered pulse, if the signal does not becomes high before the last instruction of the ISR, then the same interrupt will be caused again, so monitoring of pulse is required for a level triggered pulse.
