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 1Khz. 8 Mhz. 2 Mhz. 2 Khz. 1Khz. 8 Mhz. 2 Mhz. 2 Khz. ANSWER DOWNLOAD EXAMIANS APP
Microprocessor Assertion(A): Segment override prefix (SOP) is used when a default offset register is not used with its default base segment register but with a different base register. Reason(R): The offset registers IP and SP can never be associated with any other segment registers apart from their respective default segments. Both A & R are true but R is not the correct explanation of A. A is false but R is true. Both A & R are true and R is the correct explanation of A. A is true but R is false. Both A & R are true but R is not the correct explanation of A. A is false but R is true. Both A & R are true and R is the correct explanation of A. A is true but R is false.
