Exception Sources and Vector Table

The exception sources are classified as shown in figure 4.1. Different vector addresses are

assigned to different exception sources.

Table 4.2 lists the exception sources and their vector addresses.

Exception

sources

Reset

Interrupts

Trap instruction

Power-on reset

Manual reset

External interrupts: NMI, IRQ7 to IRQ0

Internal interrupts: 34 interrupt sources in

on-chip supporting modules

Figure 4.1 Exception Sources

In modes 6 and 7, the on-chip ROM available for use on the H8S/2246 and H8S/2245 after a

power-on reset is the 64-kbyte area comprising addresses H'000000 to H'00FFFF. Care is required

when setting vector addresses. In this case, clearing the EAE bit in BCRL enables the 128-kbyte

area comprising addresses H'000000 to H'01FFFF to be used for the on-chip ROM.
