Table 3. Value set in processor interrupt level (IPL) during an
interrupt
As shown in Figure 9, there are three different interrupt priority
resolution time from which one is selected by software. After the
selected time has elapsed, the highest priority is determined and
is processed after the currently executing instruction has been
completed.
The time is selected with bits 4 and 5 of the processor mode reg-
ister (address 5E
16
) shown in Figure 10. Table 4 shows the
relationship between these bits and the number of cycles. After a
reset, the processor mode register is initialized to “00
16
” and
therefore, the longest time is selected.
However, the shortest time should be selected by software.
