Section 4 Exception Handling
4.1.3
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.
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.
