6.12 EXCEPTION PROCESSING EXECUTION TIMES
Table 6-14 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 num-
ber of write cycles are shown in the previously described format. The number of clock peri-
ods, 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 (+).
+ Add effective address calculation time.
