Operands:
S: Source device D: Destination device n: number of bytes to be converted (n = 1~256)
Explanations:
1. 16-bit conversion mode: When M1161 = OFF, the instruction converts n bytes of ASCII codes
starting from S into Hex data in byte mode and send them to high byte and low byte of D. n =
the converted number of bytes.
2. 8-bit conversion mode: When M1161 = ON, the instruction converts n bytes (low bytes only) of
ASCII codes starting from S into Hex data in byte mode and send them to the low byte of D. n
= the converted number of bytes. (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 4 bytes of ASCII codes stored in registers D20~ D21 into Hex value
and send the result in byte mode to register D10. n = 4
