Subtracting 32-bit binary block data
DBK-(P)(_U)
These instructions subtract (n) point(s) of 32-bit binary data from the device specified by (s1) and the (n) point(s) of 32-bit
binary data from the device specified by (s2), and store the results of subtraction in the device specified by (d).

Processing details
• These instructions subtract (n) point(s) of 32-bit binary data from the device specified by (s1) and the (n) point(s) of 32-bit
binary data from the device specified by (s2), and store the results of subtraction in the device specified by (d).
• Block subtraction is performed in 32-bit units.
Ex.
If device is specified for (s2) (signed)
If constant is specified for (s2) (signed)
