Microprocessor The reason for the presence of ALE pin in 8085, but not in 6800 is that 8085 has 5 interrupts lines, whereas 6800 has only two None 8085 has multiplexed bus, whereas 6800 does not have 8085 uses I/O mapped I/O, whereas 6800 uses memory mapped I/O 8085 has 5 interrupts lines, whereas 6800 has only two None 8085 has multiplexed bus, whereas 6800 does not have 8085 uses I/O mapped I/O, whereas 6800 uses memory mapped I/O 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. A is true but R is false. A is false but R is true. Both A & R are true and R is the correct explanation of A. Both A & R are true but R is not the correct explanation of A . A is true but R is false. A is false but R is true.
