Operands:
S
: Source data
D
: Destination of the result
n
: Number of digits to convert (
n
=1~256)
Description:
1. 16-bit conversion mode: When M1161=OFF (16-bit conversion mode), read
n
hexadecimal
characters from source
S
and convert them to ASCII. Then, store the result into high and low
bytes of
D
.
2. 8-bit conversion mode: When M1161=ON (8-bit conversion mode), read
n
hexadecimal
characters from source
S
and convert them to ASCII. Then, store the result into the low byte of
D
(high byte of
D
will be set to 0).
3. Available range for Hex data: 0~9, A~F.
4. ELC-PB, ELCB-PB series doesn’t support the index registers E, F.
Program Example 1:
1. When M1161=OFF, conversion mode is 16-bit.
2. When X0=ON, read four hexadecimal characters from D10 and convert them into ASCII. Then,
store the converted characters in the register started 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
