Shutdown mode This mode has the entire device powered down. All state, including cache
and TCM state, must be saved externally. After power-up, the assertion of
reset returns the processor to the run state.
Standby mode This mode disables most of the clocks of the device, while keeping the
device powered up. This reduces the power drawn to the static leakage
current and the minimal clock power overhead required to enable the
device to wake up from the Standby mode.
For more information on the power management features, see Chapter 10 Power Control.
