A portion of an assembly language program written for an 8-bit microprocessor is given below along with explanations. The code is intended to introduce software time delay. The processor is driven by a 5 MHz clock. The time delay (in
s) introduced by the program is ______.Instruction | Explanation |
|---|---|
MVI B, 64H | Move immediate the given byte into register B. Takes 7 clock periods. |
LOOP: DCR B | Decrement register B. Affects Flags. Takes 4 clock periods. |
JNZ LOOP | Jump to address with Label LOOP if zero flag is not set. Takes 10 clock periods when jump is performed and 7 clock periods when jump is not performed. |
