Write an assembly program that copies all the memory locations from $0220 to $02D2 to memory locations $0420

Write an assembly program that copies all the memory locations from $0220 to $02D2 to memory locations $0420 to $04D2. Also sketch a flowchart diagram. Steps: 1- First you need to calculate the number of locations in the range above (subtract the end address from the start address). 2- Set a counter to this number. 3- Set X-Register as pointer to memory S0220 and set Y-Register as pointer to S0420. 4- In a loop, you will copy the memory at pointer X location to a register (Use LD instruction) then copy the value in this register to the memory at the pointer Y (use ST instruction). 5- Increment the two pointers and decrement the counter. 6- Check if the counter is zero (BRNE). 7- If not zero, jump to step 4 (read another location). If zero exit the loop.
