2.4.4 Lockup
The processor enters a lockup state if a hard fault occurs when executing the NMI or hard fault handlers.
When the processor is in lockup state it does not execute any instructions. The processor remains in
lockup state until either:
it is reset
an NMI occurs.
Note
If lockup state occurs from the NMI handler a subsequent NMI does not cause the
processor to leave lockup state.
2.5 Power management
The Cortex-M3 processor sleep modes reduce power consumption:
Sleep mode (Energy Mode 1) stops the processor clock
Deep sleep mode (Energy Mode 2/3) stops the high frequency oscillators and HFPERCLK/
HFCORECLK as well as flash memory.
The SLEEPDEEP bit of the SCR selects which sleep mode is used, see Section 4.3.7 (p. 100) . For
more information about the behavior of the sleep modes see the EMU documentation in the reference
manual for the device.
This section describes the mechanisms for entering sleep mode, and the conditions for waking up from
sleep mode.
2.5.1 Entering sleep mode
This section describes the mechanisms software can use to put the processor into sleep mode.
The system can generate spurious wakeup events, for example a debug operation wakes up the
processor. Therefore software must be able to put the processor back into sleep mode after such an
event. A program might have an idle loop to put the processor back to sleep mode.
2.5.1.1 Wait for interrupt
The wait for interrupt instruction, WFI, causes immediate entry to sleep mode. When the processor
executes a WFI instruction it stops executing instructions and enters sleep mode. See Section 3.10.12 (p.
86) for more information.
2.5.1.2 Wait for event
The wait for event instruction, WFE, causes entry to sleep mode conditional on the value of an one-bit
event register. When the processor executes a WFE instruction, it checks this register:
