GSWD

The Get Status Word (GSWD) instruction retrieves the Sign Flag, Zero Flag, Overflow Flag, and Carry Flag and places them into the register specified. The format of this opcode is as follows.

   0000:0000:0011:00rr

   where:
       rr   indicates the target register
            such that:
                rr == 00    indicates register R0
                rr == 01    indicates register R1
                rr == 10    indicates register R2
                rr == 11    indicates register R3

After the GSWD instruction is executed, the specified register will contain the values of S, Z, O, and C in the format as follows.

   SZOC:0000:SZOC:0000

   where:
       S    indicates the value of the Sign Flag
       Z    indicates the value of the Zero Flag
       O    indicates the value of the Overflow Flag
       C    indicates the value of the Carry Flag
