Operands:
S: Start device for source data
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.

4. When n = 4, the bit structure will be as:
