Low Power Modes
3.2
Low Power Modes
The following features are available to support applications which require low power.
Four modes of operation:
— RUN
—WAIT
— DOZE
—STOP
Ability to shut down most peripherals independently.
Ability to shut down the external CLKOUT pin.
There are four modes of operation: RUN, WAIT, DOZE, and STOP. The system enters a low power mode
when the user programs the low power bits (LPMD) in the LPCR (Low Power Control Register) in the CIM
before the CPU core executes a STOP instruction. This idles the CPU with no cycles active. The LPMD bits
indicate to the system and clock controller to power down and stop the clocks appropriately. During STOP
mode, the system clock is stopped low.
A wakeup event is required to exit a low power mode and return back to RUN mode. Wakeup events consist
of any of the following conditions. See the following sections for more details.
1. Any type of reset.
2. Assertion of the BKPT pin to request entry into Debug mode.
3. Debug request bit in the BDM control register to request entry into debug mode.
4. Any valid interrupt request.
3.2.1
RUN Mode
RUN mode is the normal system operating mode. Current consumption in this mode is related directly to
the frequency chosen for the system clock.
