PRELIMINARY
Notice: This is not a final specification.
Some parametric limits are subject to change.
SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER
As shown in Figure 13, there are three different interrupt priority de-
tection time from which one is selected by software. After the se-
lected time has elapsed, the highest priority is determined and is
processed after the currently executing instruction has been com-
pleted.
The time is selected with bits 4 and 5 of the processor mode register
0 (address 5E
16
) shown in Figure 14. Table 5 shows the relationship
between these bits and the number of cycles. After a reset, the pro-
cessor mode register 0 is initialized to “00
16.
” Therefore, the longest
time is automatically set, however, the shortest time must be se-
lected by software.
