MVN  Wd, Wm{, shift #amount}    ; 32-bit general registers

Equivalent to ORN Wd, WZR, Wm{, shift #amount}

MVN  Xd, Xm{, shift #amount}    ; 64-bit general registers

Equivalent to ORN Xd, XZR, Xm{, shift #amount}

Wd

Is the 32-bit name of the general-purpose destination register, in the range 0 to 31.

Wm
