The value indicated by the displace-
ment (dsp) plus the content of the
address register (A0/A1)—added
without the sign bits—is the effective
address for the operation.
However, if the addition results in a
value exceeding 0FFFF

returns to 00000
The address indicated by the content
of the static base register (SB) plus
the value indicated by the displace-

bits—is the effective address for the
operation.
