Performing a 32-bit test

DTEST(P)
These instructions take bit data at position specified by (s2) from device specified by (s1) and write to bit device specified by
(d).

Processing details
• These instructions take bit data at position specified by (s2) from device specified by (s1), (s1) +1 and write to bit device
specified by (d).
(1)
b31 ∙∙∙ b21 ∙∙∙ b16
(s1)+1
(1): (s2) bit (When (s2)=21)
• If relevant bit is "0", device specified by (d) is turned OFF, and if it is "1", device is turned ON.
• For (s2) specify the bit position (0 to 31) of double word data. If 32 or more is specified for (s2), the value of the remainder
of (s2)32 is the bit position.
Ex.
For (s2) = 34, the remainder for 3432 is "2", so it becomes data of b2.
