Address Formats
Table 4-1 summarizes the address formats that are acceptable for
address parameters in debugger command lines.
Table 4-1. Debugger Address Parameter Formats
Format Example Description
N 140 Absolute address+contents of automatic offset register.
N+Rn 130+R5 Absolute address+contents of the specified offset
register (not an assembler-accepted syntax).
(An) (A1) Address register indirect. (Also post-increment, pre-
decrement)
(d,An) or
d(An)
(120,A1)
120(A1)
Address register indirect with displacement (two
formats accepted).
(d,An,Xn) or
d(An,Xn)
(&120,A1,D2)
&120(A1,D2)
Address register indirect with index and displacement
(two formats accepted).
([bd,An,Xn],od) ([C,A2,A3],&100) Memory indirect preindexed.
([bd,An],Xn,od) ([12,A3],D2,&10) Memory indirect postindexed.
For the memory indirect modes, fields can be omitted.
For example, three of many permutations are as follows:
([,An],od) ([,A1],4)
([bd]) ([FC1E])
([bd,,Xn]) ([8,,D2])
Notes
N — Absolute address (any valid expression).
An — Address register n.
Xn — Index register n (An or Dn).
d — Displacement (any valid expression).
bd — Base displacement (any valid expression).
od — Outer displacement (any valid expression).
n — Register number (0 to 7).
Rn — Offset register n.
