25 Block Data Operation – FNC190 to FNC199
25.3 FNC194~199 – BKCMP=, >, <, < >, <=, >= / Block Data Compare
Explanation of function and operation
1. 16-bit operation (BKCMP=, >, <, <>, <=, >= / BKCMP=P, >P, <P, <>P, <=P, and >=P)
1) "n" 16-bit binary data starting from are compared with "n" 16-bit binary data starting from , and the
comparison result is stored in "n" points starting from .
2) A constant can be directly specified in .
3) The table below shows the comparison result in each instruction:
4) When the comparison result is ON (1) in all of "n" points starting from , M8090 (block comparison signal)
turns ON.
