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. 8 Mhz. 1Khz. 2 Mhz. 2 Khz. 8 Mhz. 1Khz. ANSWER DOWNLOAD EXAMIANS APP
Microprocessor _____________is used to read the status of the hardware interrupts (RST 7.5, RST 6.5, RST 5.5) by loading into the A register a byte which defines the condition of the mask bits for the interrupts. RIM DI EI SIM RIM DI EI SIM ANSWER DOWNLOAD EXAMIANS APP
Microprocessor A good assembly language programmer should use general purpose registers rather than memory in maximum possible ways for data processing. This is because: Data processing with registers takes fewer cycles than that with memory Data processing with memory requires more instructions in the program than that with registers Data processing with registers is easier than with memory Of limited set of instructions for data processing with memory Data processing with registers takes fewer cycles than that with memory Data processing with memory requires more instructions in the program than that with registers Data processing with registers is easier than with memory Of limited set of instructions for data processing with memory ANSWER DOWNLOAD EXAMIANS APP
