Microprocessor The reason for the presence of ALE pin in 8085, but not in 6800 is that None 8085 has 5 interrupts lines, whereas 6800 has only two 8085 uses I/O mapped I/O, whereas 6800 uses memory mapped I/O 8085 has multiplexed bus, whereas 6800 does not have None 8085 has 5 interrupts lines, whereas 6800 has only two 8085 uses I/O mapped I/O, whereas 6800 uses memory mapped I/O 8085 has multiplexed bus, whereas 6800 does not have ANSWER DOWNLOAD EXAMIANS APP

Microprocessor Assertion (A): Each memory chip has its own address latch. Reason (R): ALE signal comes out of microprocessor 8085 and goes to memory chip. Both A and R are correct but R is not correct explanation of A A is wrong R is correct Both A and R are correct and R is correct explanation of A A is correct R is wrong Both A and R are correct but R is not correct explanation of A A is wrong R is correct Both A and R are correct and R is correct explanation of A A is correct R is wrong ANSWER DOWNLOAD EXAMIANS APP
Microprocessor Assertion(A): Ready signal of microprocessor is used to detect whether a peripheral is ready for the data transfer or not. Reason(R): In the microprocessor during data transfer operations, the wait states are added by forcing the ready signal low. 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 false but R is true. A is true but R is false. 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 false but R is true. A is true but R is false. ANSWER DOWNLOAD EXAMIANS APP
