`SBC` (subtract with borrow) Tags: NVZC

Description:

It subtracts the byte of data from the accumulator along with the Carry flag (C bit). If the data is larger than the accumulator, it will clear C bit (which means a borrow), otherwise it sets the C bit. The result of the subtraction remains in the accumulator.

Example:

        SBC #0;        ; subtract zero from A register
          SBC (src),Y
        SBC date,X
