Halt the processor if the ErrorFlag is set
Table 3.5 Error flags
ErrorFlag is a pair of flags , one for each priority, set by the processor if an integer error
or integer overflow error occurs and the corresponding trap is not enabled. The
processor will immediately halt if the HaltOnError flag is also set, or will contin ue
