The number of clock periods periods shown in this table includes the time to
fetch immediate operands, perform the operations, store the results and read
the next operation. The number of bus read and write cycles is shown in
parenthesis as (r/w). The number of clock periods and the number of read and
write cycles must be added respectively to those of the effective address
calculation where indicated.
