Draw a flowchart to do the following: Note: Assumed that all numbers are $\backslash (\backslash$geq $\backslash )$ signed numbers.

Load register R$20$ with the contents of memory location $\backslash (\backslash$$ $810\backslash )$

Load register R$21$ with the contents of memory location $\backslash$$$811$

Compare R$20$ and R$21$

If $\backslash (\backslash$mathrm$\{$R$\}20\backslash$geq $\backslash$mathrm$\{$R$\}21\backslash ),$

Then increment R$22$ and write $\backslash$$$00$ to memory location $\backslash$$$822$

Else decrement R$22$ and write $\backslash$$FF to memory location $\backslash (\backslash$$ $823\backslash )$

Clear Register R$21$
