2.8.2 Program Execution State
In this state the CPU executes program instructions in normal sequence.
2.8.3 Exception-Handling State
The exception-handling state is a transient state that occurs when the CPU alters the normal
program flow due to a reset, interrupt, or trap instruction. The CPU fetches a starting address from
the exception vector table and branches to that address. In interrupt and trap exception handling
the CPU references the stack pointer (ER7) and saves the program counter and condition code
register.
Types of Exception Handling and Their Priority: Exception handling is performed for resets,
interrupts, and trap instructions. Table 2-14 indicates the types of exception handling and their
priority. Trap instruction exceptions are accepted at all times in the program execution state.
