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
comparison result is stored in "n" points starting from

BKCMP>(FNC195)
BKCMP<(FNC196)
BKCMP<>(FNC197)
BKCMP<=(FNC198)
BKCMP>=(FNC199)
4) When the comparison result is ON (1) in all of "n" points starting from
