Operands:
S
: Start device for source data
D
: Start device for storing the converted result
n
: Number of bits to be converted
Explanations:
1. Range of
n
: 1 ~ 256
2. See the specifications of each model for their range of use.
3. Flag: M1161 (8/16 bit mode switch)
4. 16-bit conversion mode: When M1161 = Off, the instruction converts every bit of the hex data in
S
into ASCII
codes and send them to the 8 high bits and 8 low bits of
D
.
n
= the converted number of bits.
5. 8-bit conversion mode: When M1161 = On, the instruction converts every bit of the hex data in
S
into ASCII
codes and send them to the 8 low bits of
D
.
n
= the number of converted bits. (All 8 high bits of
D
= 0)
Program Example 1:
1. M1161 = Off: The 16-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) = 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
4. When
n
= 4, the bit structure will be as:
0 0 0 0 0 0 0 1 0 0 1 0 0 0 1 1
