Microprocessor The reason for the presence of ALE pin in 8085, but not in 6800 is that 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 8085 has 5 interrupts lines, whereas 6800 has only two None ANSWER DOWNLOAD EXAMIANS APP
Microprocessor While using a frequency counter for measuring frequency, two modes of measurement are possible: Period time Frequency mode There is a ‘cross-over frequency’ below which the period mode is preferred. Assuming the crystal oscillator frequency to be 4MHz, the crossover frequency is given by 2 Mhz. 2 Khz. 1Khz. 8 Mhz. 2 Mhz. 2 Khz. 1Khz. 8 Mhz. ANSWER DOWNLOAD EXAMIANS APP
