Bitwise AND
Sets $t1 to $t2 AND $t3, or an immediate, so each result bit is 1 only where both inputs are 1.

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. uimm16- An unsigned 16-bit immediate,
0to65535.
Each bit of $t1 is 1 only if the corresponding bit is 1 in both $t2 and $t3. Commonly used to mask (isolate) specific bits in a value.
# Initialize both inputs, then execute and with initialized inputs. Inspect $t2: 3.
