Function
NMI set-pending bit.
Write:
0 = no effect
1 = changes NMI exception state to pending.
Read:
0 = NMI exception is not pending
1 = NMI exception is pending.
Because NMI is the highest-priority exception, normally
the processor enters the NMI exception handler as soon
as it detects a write of 1 to this bit. Entering the handler
then clears this bit to 0. This means a read of this bit by
the NMI exception handler returns 1 only if the NMI
signal is reasserted while the processor is executing that
handler.
Reserved.
PendSV set-pending bit.
Write:
0 = no effect
1 = changes PendSV exception state to pending.
Read:
0 = PendSV exception is not pending
1 = PendSV exception is pending.
Writing 1 to this bit is the only way to set the PendSV
exception state to pending.
PendSV clear-pending bit.
Write:
0 = no effect
1 = removes the pending state from the PendSV
exception.
SysTick exception set-pending bit.
Write:
0 = no effect
1 = changes SysTick exception state to pending.
Read:
0 = SysTick exception is not pending
1 = SysTick exception is pending.
