Microprocessor Assertion(A): Monostablemultivibrators (IC74121) are used in a microprocessor based system for frequency measurement. Reason(R): Microprocessor counts the number of interrupt signals/second or within a specified interval through ISR. Both A & R are true and R is the correct explanation of A. A is true but R is false. A is false but R is true. Both A & R are true but R is not the correct explanation of A. Both A & R are true and R is the correct explanation of A. A is true but R is false. A is false but R is true. Both A & R are true but R is not the correct explanation of A. ANSWER DOWNLOAD EXAMIANS APP
Microprocessor The reason for the presence of ALE pin in 8085, but not in 6800 is that 8085 uses I/O mapped I/O, whereas 6800 uses memory mapped I/O 8085 has 5 interrupts lines, whereas 6800 has only two 8085 has multiplexed bus, whereas 6800 does not have None 8085 uses I/O mapped I/O, whereas 6800 uses memory mapped I/O 8085 has 5 interrupts lines, whereas 6800 has only two 8085 has multiplexed bus, whereas 6800 does not have None ANSWER DOWNLOAD EXAMIANS APP
