Operands:
S: Source device D: Destination device n: Number of nibbles to be converted (n = 1~256)
Explanations:
1. 16-bit conversion mode: When M1161 = OFF, the instruction converts every nibble of the Hex
data in S into ASCII codes and send them to the higher 8 bits and lower 8 bits of D. n = the
converted number of nibbles.
2. 8-bit conversion mode: When M1161 = ON, the instruction converts every nibble of the Hex
data in S into ASCII codes and send them to the lower 8 bits of D. n = the number of converted
nibbles. (All higher 8 bits of D = 0).
3. Flag: M1161 (8/16 bit mode switch)
4. Available range for Hex data: 0~9, A~F
Program Example 1:
1. M1161 = OFF, 16-bit conversion.
2. When X0 = ON, convert the 4 hex values (nibbles) in D10 into ASCII codes and send the result
to registers starting from D20.

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) = CDEF H ‘3’ = 33H ‘7’ = 37H ‘B’ = 42H
