Explanation:
1. n singed decimal values in the registers starting from the register specified by S
1
are
compared with the singed decimal value in the register specified by S
2
, and the comparison
results are stored in the registers D~D+4.
Device
Description
D
Number of equal values
D+1
Data number of the first equal
value
D+2
Data number of the last equal
value
D+3
Data number of the minimum
value
D+4
Data number of the maximum
value
2. The operand n used in the 16-bit instruction should be within the range between 1 and 256.
The operand n used in the 32-bit instruction should be within the range between 1 and 128.
3. Only the 32-bit instructions can use the 32-bit counter.
