5.4 Exception Handling and Servicing Flowcharts
The remainder of this chapter contains flowcharts for the following
exceptions and guidelines for their handlers:
• general exceptions and their exception handler
• TLB/XTLB miss exception and their exception handler
• cache error exception and its handler
• reset, soft reset and NMI exceptions, and a guideline to their
handler.
Generally speaking, the exceptions are handled by hardware (HW); the
exceptions are then serviced by software (SW).
