2.5.1
The CPU has four processing states: reset, exception processing, program execution and power-
down. Figure 2.6 shows the transitions between the states.
Reset State: The CPU resets in the reset state. When the RES pin level goes low, a power-on reset
results.
Exception Processing State: The exception processing state is a transient state that occurs when
exception processing sources such as resets or interrupts alter the CPU’s processing state flow.
