Microprocessor The program counter in a 8085 micro-processor is a 16-bit register, because 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 It has to fetch two 8-bit data at a time There are 16 address lines 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 memory requires more instructions in the program than that with registers Of limited set of instructions for data processing with memory Data processing with registers takes fewer cycles than that with memory Data processing with registers is easier than with memory Data processing with memory requires more instructions in the program than that with registers Of limited set of instructions for data processing with memory Data processing with registers takes fewer cycles than that with memory Data processing with registers is easier than with memory ANSWER DOWNLOAD EXAMIANS APP
