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 a software time delay. The processor is driven by a $5\; MHz$ clock. The time delay (in $\mu$s) introduced by the program is _____________.
$\text{MVI B, 64H}$ : Move immediate the given byte into register B. Takes 7 clock periods.
$\text{LOOP : DCR B}$ : Decrement register B. Affects Flags. Take 4c clock periods.
$\text{JNZ LOOP}$ : 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.
