address parameters in debugger command lines. 

N

140

Absolute address+contents of automatic offset register. 

N+Rn

130+R5

Absolute address+contents of the speciÞed 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, Þelds can be omitted.
For example, three of many permutations are as follows:

([,An],od)

([,A1],4)

([bd])

([FC1E])

([bd,,Xn])

([8,,D2])
