Operation
RS1 | RS2 ⇒ RD
RD | IMM16⇒ RD (translates to ORL RD, #IMM16[7:0]; ORH RD, #IMM16[15:8]
Performs a bit wise logical OR between two 16 bit values and stores the result in the destination
register RD.

∆ ∆ 0—
N: Set if bit 15 of the result is set; cleared otherwise.
Z: Set if the result is $0000; cleared otherwise.
Refer to ORH instruction for #IMM16 operations.
V: 0; cleared.
C: Not affected.
