6 BASIC INSTRUCTIONS
6.3 Logical Operation Instructions
Performing an XNOR operation on 16-bit block data
BKXNR(P)
These instructions exclusive NOR contents of (n) point(s) from the device specified by (s1) and (n) point(s) from the device
specified by (s2), and store the results in the devices specified by (d) onwards.

Error code
(SD0/SD8067) Description
2820 The range of (n) point(s) of data starting from the device specified by (s1), (s2), or (d) exceed the corresponding device range.
2821 Device range of (n) point(s) from (s1) partially overlaps with device range of (n) point(s) from (d).
(Does not apply when same device has been specified for (s1) and (d).)
Device range of (n) point(s) from (s2) partially overlaps with device range of (n) point(s) from (d).
