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.
X0
ASCI D10 D20 K4
M1000
M1161
3. Assume
(D10) = 0123 H ‘0’ = 30H ‘4’ = 34H ‘8’ = 38H
(D11) = 4567 H ‘1’ = 31H ‘5’ = 35H ‘9’ = 39H
(D12) = 89AB H ‘2’ = 32H ‘6’ = 36H ‘A’ = 41H
(D13) = CDEFH ‘3’ = 33H ‘7’ = 37H ‘B’ = 42H
4. When n = 2, the bit structure will be as:
0 0 0 0 0 0 0 1 0 0 1 0 0 0 1 1
