PRIGROUP
R/W
Interrupt priority grouping
000: seven bits of pre-emption priority, one bit of subpriority
001: six bits of pre-emption priority, two bits of subpriority
010: five bits of pre-emption priority, three bits of subpriority
011: four bits of pre-emption priority, four bits of subpriority
100: three bits of pre-emption priority, five bits of subpriority
101: two bits of pre-emption priority, six bits of subpriority
110: one bit of pre-emption priority, seven bits of subpriority
111: no pre-emption priority, eight bits of subpriority

SYSRESET
REQ
R/W
System Reset Request.
1=CPU outputs a SYSRESETREQ signal. (note2)

VECTCLR
ACTIVE
R/W
Clear active vector bit
1: clear all state information for active NMI, fault, and interrupts
0: do not clear.
This bit self-clears.
It is the responsibility of the application to reinitialize the stack.
0
VECTRESET
R/W
System Reset bit
1: reset system
0: do not reset system
Resets the system, with the exception of debug components (FPB, DWT and ITM) by setting "1" and this
bit is also zero cleared.
Note 1:
Little-endian is the default memory format for this product.
Note 2:
When
<
SYSRESETREQ
>
is output, warm reset is performed on this product. <SYSRESETREQ> is
cleared by warm reset.
