9.12 EXCEPTION PROCESSING EXECUTION TIMES
Table 9-19 lists the timing data for exception processing. The numbers of clock periods
include the times for all stacking, the vector fetch, and the fetch of the first instruction of
the handler routine. The total number of clock periods, the number of read cycles, and the
number of write cycles are shown in the previously described format. The number of clock
periods, the number of read cycles, and the number of write cycles, respectively, must be
added to those of the effective address calculation where indicated by a plus sign (+).
