1: PendSV exception is pending.
Writing 1 to this bit is the only way to set the PendSV exception state to pending.
• PENDSVCLR: PendSV Clear-pending
Write:
0: no effect.
1: removes the pending state from the PendSV exception.
• PENDSTSET: SysTick Exception Set-pending
Write:
0: no effect.
1: changes SysTick exception state to pending.
Read:
0: SysTick exception is not pending.
1: SysTick exception is pending.
• PENDSTCLR: SysTick Exception Clear-pending
Write:
0: no effect.
1: removes the pending state from the SysTick exception.
This bit is Write-only. On a register read, its value is Unknown.
• ISRPENDING: Interrupt Pending flag (excluding NMI and Faults)
0: interrupt not pending.
1: interrupt pending.
• VECTPENDING: Exception number of the highest priority pending enabled exception
0: no pending exceptions.
Nonzero: the exception number of the highest priority pending enabled exception.
The value indicated by this field includes the effect of the BASEPRI and FAULTMASK registers, but not any effect of the
PRIMASK register.
• RETTOBASE: Preempted Active Exceptions present or not
0: there are preempted active exceptions to execute.
1: there are no active exceptions, or the currently-executing exception is the only active exception.
• VECTACTIVE: Active Exception Number contained
0: Thread mode.
Nonzero: The exception number of the currently active exception. The value is the same as
gram Status Register”
Subtract 16 from this value to obtain the IRQ number required to index into the Interrupt Clear-Enable, Set-Enable, Clear-
Pending, Set-Pending, or Priority Registers, see
