The get_ab[bwl] tables are used by EMU68 to calculate operands effective address and are indexed by operand addressing mode. The called function do everything neccessary to update processor state like address register increment or decrement. Function parameter is register number coded in three bit 0 to 2 of 68k opcode. When the mode is 7, register parameter is used as an index in a second level function table for extended addressing mode.
