Comments

rr0nnnnn

n,r

–n,r

5-bit constant offset

n = –16 to +15

rr can specify X, Y, SP, or PC

111rr0zs

n,r

–n,r

Constant offset (9- or 16-bit signed)

0 = 9-bit with sign in LSB of postbyte (s)

1 = 16-bit

if z = s = 1, 16-bit offset indexed-indirect (see below)

rr can specify X, Y, SP, or PC

rr1pnnnn

n,–r

n,+r

n,r–

n,r+

Auto predecrement, preincrement, postdecrement, or postincrement;

p = pre-(0) or post-(1), n = –8 to –1, +1 to +8

rr can specify X, Y, or SP (PC not a valid choice)

111rr1aa

A,r

B,r

D,r

Accumulator offset (unsigned 8-bit or 16-bit)

aa - 00 = A

01 = B

10 = D (16-bit)

11 = see accumulator D offset indexed-indirect

rr can specify X, Y, SP, or PC

111rr011

[n,r]

16-bit offset indexed-indirect

rr can specify X, Y, SP, or PC

111rr111

[D,r]

Accumulator D offset indexed-indirect

rr can specify X, Y, SP, or PC
