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