Operand 2
An operand is the part of the instruction that references data or a peripheral device.
Operand 2 is listed in Table 1-4.
DB decrement before EA, empty ascending
Mode 4, store <a_mode4S> IA, increment after FD, full descending
IB, increment before ED, empty descending
DA, decrement after FA, full ascending
DB decrement before EA, empty ascending
Mode 5, coprocessor data transfer <a_mode5> Immediate offset
