DXNR(P) [using three operands]
These instructions exclusive NOR each bit of 32-bit binary data from the device specified by (s1) and each bit of 32-bit binary
data from device specified by (s2), and store the results in the device specified by (d).
■Descriptions, ranges, and data types
■Applicable devices
• These instructions exclusive NOR each bit of 32-bit binary data from the device specified by (s1) and each bit of 32-bit
binary data from device specified by (s2), and store the results in the device specified by (d).
• Bit devices subsequent to number of points by nibble specification are calculated as 0.
There is no operation error.
