nor
Bitwise NOR
Sets $t1 to the bitwise NOR of $t2 and $t3, so each result bit is 1 only where both inputs are 0.

Operands
$t1- Any general-purpose register,
$0to$31, using its numeric or named spelling, such as$8or$t0($zerois$0;$rais$31). $t2- A general-purpose register. It may be the same register as
$t1. $t3- A general-purpose register. It may be the same register as
$t1.
Each bit of $t1 is 1 only if the corresponding bit is 0 in both $t2 and $t3. Tip: 'nor $t1,$t2,$zero' computes a bitwise NOT of $t2, since MIPS has no dedicated NOT instruction.
# Initialize both inputs, then execute nor with initialized inputs. Inspect $t2: 4294967288.
