Functional Description
Data Sheet

V2.0, 2009-03
The XC2735X includes an excellent mechanism to identify and process exceptions or
error conditions that arise during run-time, the so-called ‘Hardware Traps’. A hardware
trap causes an immediate non-maskable system reaction similar to a standard interrupt
service (branching to a dedicated vector table location). The occurrence of a hardware
trap is also indicated by a single bit in the trap flag register (TFR). Unless another higher-
priority trap service is in progress, a hardware trap will interrupt any ongoing program
execution. In turn, hardware trap services can normally not be interrupted by standard
or PEC interrupts.
Table 8 shows all possible exceptions or error conditions that can arise during runtime:

Vector
Location1)
1) Register VECSEG defines the segment where the vector table is located to.
Bitfield VECSC in register CPUCON1 defines the distance between two adjacent vectors. This table
represents the default setting, with a distance of 4 (two words) between two vectors.
