(An)
(d,An) or
d(An)
(d,An,Xn) or
d(An,Xn)
([bd,An,Xn],od) ([C,A2,A3],&100) Memory indirect preindexed.
([bd,An],Xn,od)
For the memory indirect modes, Þelds can be omitted.
For example, three of many permutations are as follows:
([,An],od)
([bd])
([bd,,Xn])
Notes
N Ñ Absolute address (any valid expression).
An Ñ Address register n.
Xn Ñ Index register n (An or Dn).
d Ñ Displacement (any valid expression).
bd Ñ Base displacement (any valid expression).
od Ñ Outer displacement (any valid expression).
n Ñ Register number (0 to 7).
Rn Ñ Offset register n.
