Bits
Name
Function
[4]
SEVONPEND
Send Event on Pending bit:
0 = only enabled interrupts or events can wakeup the processor, disabled interrupts are
excluded1 = enabled events and all interrupts, including disabled interrupts, can wakeup the
processor.
When an event or interrupt enters pending state, the event signal wakes up the processor
from WFE. If the processor is not waiting for an event, the event is registered and affects the
next WFE.
The processor also wakes up on execution of an SEV instruction or an external event.

Reserved.
[2]
SLEEPDEEP
Controls whether the processor uses sleep or deep sleep as its low power mode:
0 = sleep
1 = deep sleep.
[1]
SLEEPONEXIT
Indicates sleep-on-exit when returning from Handler mode to Thread mode:
0 = do not sleep when returning to Thread mode.
1 = enter sleep, or deep sleep, on return from an ISR.
Setting this bit to 1 enables an interrupt driven application to avoid returning to an empty main
application.

Reserved.
4.3.8 Configuration and Control Register
The CCR controls entry to Thread mode and enables:
the handlers for NMI, hard fault and faults escalated by FAULTMASK to ignore bus faults
trapping of divide by zero and unaligned accesses
access to the STIR by unprivileged software, see Section 4.2.8 (p. 93) .
See the register summary in Table 4.12 (p. 94) for the CCR attributes.
