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

		M1001		M1161
		X0		HEX	D20	D10	K4
3. Assume:
			S	ASCII code		HEX		S	ASCII code	HEX
						conversion				conversion
	D20 low byte			H 43		“C”		D24 low byte	H 34	“4”
	D20 high byte			H 44		“D”		D24 high byte	H 35	“5”
	D21 low byte			H 45		“E”		D25 low byte	H 36	“6”
	D21 high byte			H 46		“F”		D25 high byte	H 37	“7”
	D22 low byte			H 38		“8”		D26 low byte	H 30	“0”
	D22 high byte			H 39		“9”		D26 high byte	H 31	“1”
	D23 low byte			H 41		“A”		D27 low byte	H 32	“2”
	D23 high byte			H 42		“B”		D27 high byte	H 33	“3”
