SBC
Operation
RS1 - RS2 - C
Subtracts the content of register RS2 and the value of the Carry bit from the content of register RS1 using
binary subtraction and stores the result in the destination register RD. Also the zero flag is carried forward
from the previous operation allowing 32 and more bit subtractions.
