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 is in 16-bit conversion mode. ASCII codes of the 8
high bits and 8 low bits of the hex data in
S
are converted into hex value and sent to
D
(every 4 bits as a group).
n
= the number of bits converted into ASCII codes.
5. 8-bit conversion mode: When M1161 = On, the instruction is in 8-bit conversion mode. Every bit of the hex data in
S
are converted into ASCII codes and sent 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 ASCII codes stored in the registers starting from D20 into hex value and send the
result (every 4 bits as a group) to registers starting from D10.
n
= 4.
