Explanation
The LD0000 and AND0001 instructions cause the result of the logical
AND operation in block C to be stored in the result register.
The LD0002 instruction in block D causes the result of the operation in
block C to be transferred to the stack register and the result of the logical
operation between the LD0002 and AND-NOTO003 instructions in block
D to be stored in the result register.
The OR-LD instruction causes a logical OR operation to be performed
between the result register and the stack register. The result of the logical
OR operation is then stored in the result register.
TIM
