2. 32-bit operation (DBKCMP=, >, <, <>, <=, >= / DBKCMP=P, >P, <P, <>P, <=P, and >=P)
1) "n" 32-bit binary data starting from [
+1,
] are compared with "n" 32-bit binary data starting from
[
+1,
], and the comparison result is stored in "n" points starting from [
+1,
].
2) A constant can be directly specified in [
+1,
].
3) The table below shows the comparison result for each instruction:
4) When the comparison result is ON (1) in all of "n" points starting from [
+1,
], the M8090 (block
comparison signal) turns ON.
