4.3
There are four registers related to exception handling. These are peripheral module registers, and
therefore reside in area P4. They can be accessed by specifying the address in privileged mode
only.
1. The exception event register (EXPEVT) resides at address H'FFFFFFD4, and contains a 12-bit
2. The interrupt event register (INTEVT) resides at address H'FFFFFFD8, and contains a 12-bit
3. Interrupt event register 2 (INTEVT2) resides at address H'04000000, and contains a 12-bit
4. The TRAPA exception register (TRA) resides at address H'FFFFFFD0, and contains 8-bit
The bit configurations of the EXPEVT, INTEVT, INTEVT2, and TRA registers are shown in
figure 4.3.

exception code. The exception code set in EXPEVT is that for a reset or general exception
event. The exception code is set automatically by hardware when an exception occurs.
EXPEVT can also be modified by software.
interrupt exception code or a code indicating the interrupt priority. Which is set when an
interrupt occurs depends on the interrupt source (see tables 7.4 and 7.5). The exception code or
interrupt priority code is set automatically by hardware when an exception occurs. INTEVT
can also be modified by software.
exception code. The exception code set in INTEVT2 is that for an interrupt request. The
exception code is set automatically by hardware when an exception occurs.
immediate data (imm) for the TRAPA instruction. TRA is set automatically by hardware when
a TRAPA instruction is executed. TRA can also be modified by software.
