4.1.2
EXPEVT is assigned to address H′FFFFFFD4 and consists of a 12-bit exception code. Exception
codes to be specified in EXPEVT are those for resets and general exceptions. These exception
codes are automatically specified by the hardware when an exception occurs. Only bits 11 to 0 of
EXPEVT can be re-written using the software.
Note:
4.1.3
INTEVT is assigned to address H′FFFFFFD8 and consists of the exception code or the interrupt
priority code. Whether the occurrence of an interrupt sets the exception code or the interrupt
priority code depends on the interrupt sources. (See section 8.3.5, Interrupt Exception Handling
and Priority, for details.) These exception codes and interrupt priority codes are automatically
specified by the hardware when an exception occurs. Only bits 11 to 0 in INTEVT can be re-
written using the software.
