SAM3S Preliminary
Power management programming hints
Wakeup from WFE
until the processor sets PRIMASK to zero. For more information about PRIMASK and FAULT-
MASK see
The processor wakes up if:
In addition, if the SEVONPEND bit in the SCR is set to 1, any new pending interrupt triggers an
event and wakes up the processor, even if the interrupt is disabled or has insufficient priority to
cause exception entry. For more information about the SCR see
page
ANSI C cannot directly generate the WFI and WFE instructions. The CMSIS provides the follow-
ing intrinsic functions for these instructions:
• it detects an exception with sufficient priority to cause exception entry
void __WFE(void) // Wait for Event
void __WFE(void) // Wait for Interrupt
