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.

Set if bit 15 of the result is set; cleared otherwise.
Set if the result is $0000 and Z was set before this operation; cleared otherwise.
Set if a two´s complement overflow resulted from the operation; cleared otherwise.
