Explanation of function and operation
1. 16-b16-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.
