Program Example 2:
1. M1161 = On: The 8-bit conversion mode
2. When X0 = On, convert the 4 hex values in D10 into ASCII codes and send the result to registers
starting from D20.

3. Assume
(D10) = 0ABC H
‘0’ = 30H
‘1’ = 31H
‘5’ = 35H
(D11) = 1234 H
‘A’ = 41H
‘2’ = 32H
‘6’ = 36H
(D12) = 5678 H
‘B’ = 42H
‘3’ = 33H
‘7’ = 37H
‘C’ = 43H
‘4’ = 34H
‘8’ = 38H
