Description
0:8
VECTACTIVE
R
RW
0
The exception number for the current executing
exception. 0= Thread mode. This is the same value as
IPSR[8:0]
12:20 VECTPENDING
R
RW
0
The exception number for the highest priority pending
exception. 0= No pending exceptions.
The pending state includes the effect of memory-
mapped enable and mask registers. It does not include
the PRIMASK special-purpose register qualifier.
22
ISRPENDING
R
RW
0
Indicates if an external configurable, NVIC generated,
interrupt is pending.
23
ISRPREEMPT
R
RW
0
Indicates whether a pending exception will be serviced
on exit from debug halt state.
25
PENDSTCLR
RW1C
R
0
Clears a pending SysTick, whether set here or by the
timer hardware.
26
PENDSTSETB
RW1S
RW
0
Sets a pending SysTick or reads back the current
state. Writing PENDSTSET and PENDSTCLR to '1'
concurrently is UNPREDICTABLE.
27
PENDSVCLR
RW1C
R
0
Clears a pending PendSV interrupt.
28
PENDSVSET
RW1S
RW
0
Sets a pending PendSV interrupt or reads back the
current state. Use this normally to request a context
switch. Writing PENDSVSET and PENDSVCLR to '1'
concurrently is UNPREDICTABLE.
31
NMIPENDSET
RW1S
RW
0
Activates an NMI exception or reads back the current
state.
Because NMI is the highest priority exception, it
activates as soon as it is registered.
