branches to the start address of the user-coded exception service routine found from the sum of the
contents of the vector base address and the vector offset. See section 5, Exceptions, for more
information on resets, general exceptions, and interrupts.
Program Execution State: In this state the CPU executes program instructions in sequence.
Power-Down State: In the power-down state, CPU operation halts and power consumption is
reduced. The power-down state is entered by executing a SLEEP instruction. There are three
modes in the power-down state: sleep mode, deep sleep mode, and standby mode. For details, see
section 9, Power-Down Modes.
Bus-Released State: In this state the CPU has released the bus to a device that requested it.
Transitions between the states are shown in figure 2.6.
