Delta DVP-ES2/EX2/SS2/SA2/SX2/SE manual Cmpt

3. Instruction Set

9.The 16-bit comparison values used in the 16-bit instruction are signed values. The comparison values used in the 32-bit instruction are 32-bit signed values (M1162=OFF), or floating-point numbers (M1162=ON).

10.The 16-bit data or 32-bit data is written into D. If the data length is less than 16 bits or 32 bits, the bit which does not have a corresponding value is 0. For example, if n is K8, bit0~7 have corresponding values, and bit15~31 are 0.

11.If the comparison result meets the comparison condition, the corresponding bit is 1. If the comparison result does not meet the comparison condition, the corresponding bit is 0.

Program example:

When M0 = ON, compare the 16-bit value in D0~D7 with D20~D27 and store the results in D100.

M0
CMPT	D0	D20	K8	D100

y	Content in D0~D7:
	No.	D0	D1	D2	D3	D4	D5	D6	D7
	Value	K10	K20	K30	K40	K50	K60	K70	K80
y	Content in D20~D27:
	No.	D20	D21	D22	D23	D24	D25	D26	D27
	Value	K12	K20	K33	K44	K50	K66	K70	K88

y After the comparison of CMPT instruction, the associated bit will be 1 if two devices have the same value, and other bits will all be 0. Therefore the results in D100 will be as below:

	Bit0	Bit1	Bit2	Bit3	Bit4	Bit5	Bit6	Bit7	Bit8~15
D100
	0	1	0	0	1	0	1	0	0…0
