(d) Bit addressing
This addressing is used to access 1 bit (specified with bit#3 of 3-bit data) among 1 byte of the memory space
to be manipulated by using an operand address which is the sum of the contents of a general-purpose register. (reg1) and a 16-bit displacement (disp16) sign-extended to a word length.
This addressing mode applies only to bit manipulation instructions.
