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 The program counter in a 8085 micro-processor is a 16-bit register, because It has to fetch two 8-bit data at a time There are 16 address lines It counts 16-bits at a time It facilitates the user storing 16-bit data temporarily It has to fetch two 8-bit data at a time There are 16 address lines It counts 16-bits at a time It facilitates the user storing 16-bit data temporarily ANSWER DOWNLOAD EXAMIANS APP
