B
Address as a Parameter
Many commands use
ADDR
as a parameter. The syntax accepted
by 177Bug is similar to the one accepted by the MC68060 one-line
assembler. All control addressing modes are allowed. An Òaddress
+ offset registerÓ mode is also provided.
Address Formats
Table B-2 summarizes the address formats which are acceptable for
address parameters in debugger command lines.

(A
n
)
(A1)
Address register indirect (also
post-increment, predecrement)
(
d
,A
n
) or
d
(A
n
)
(120,A1)
120(A1)
Address register indirect with
displacement (two formats
accepted).
(
d
,A
n
,
Xn
) or
d
(A
n
,
Xn
)
(&120,A1,D2)
&120(A1,D2)
Address register indirect with
index and displacement (two
formats accepted).
(
[bd
,A
n
,
Xn
],
od
)
([C,A2,A3],&100)
Memory indirect preindexed.
([
bd
,A
n
],
Xn
,
od
)
([12,A3],D2,&10)
Memory indirect postindexed.
For the memory indirect modes, Þelds can be omitted.
For example, three of many permutations are as follows:
([,A
n
],
od
)
([,A1],4)
([
bd
])
([FC1E])
([
bd
,,
Xn
])
([8,,D2])
