Effective Address Calculation

Table 2.2 shows how effective addresses are calculated in each of the addressing modes.
Arithmetic and logic instructions use register direct addressing (1). The ADD.B, ADDX, SUBX,
CMP.B, AND, OR, and XOR instructions can also use immediate addressing (6).
Data transfer instructions can use all addressing modes except program-counter relative (7) and
memory indirect (8).
Bit manipulation instructions use register direct (1), register indirect (2), or 8-bit absolute
addressing (5) to specify a byte operand, and 3-bit immediate addressing (6) to specify a bit
position in that byte. The BSET, BCLR, BNOT, and BTST instructions can also use register direct
addressing (1) to specify the bit position.
