INTERRUPT FUNCTIONS
4.1
OVERVIEW
In the
μ
PD78324, various interrupt requests generated externally or from the on-chip peripheral hardware are handled
in the following three processing modes.
Interrupt requests are classified into the following three groups.
Nonmaskable interrupt requests
Maskable interrupt requests
Interrupt requests by software
Figure 4-1 shows the maskable interrupt request processing modes. Table 4-1 gives a listing of interrupt factors which
can be processed.
