Comparing 16-bit binary block data
BKCMP
(P)(_U)
These instructions perform a comparison operation between (n) point(s) of 16-bit binary data in the device starting from the
one specified by (s1) and (n) point(s) of 16-bit binary data in the device starting from the one specified by (s2), and store the
operation result in the device specified by (d).
*1 Supported by engineering tool version "1.035M" and later.
*2 EQ is =, NE is <>, GT is >, LE is <=, LT is <, and GT is >=.
