Reserved: Write ‘0’; ignore read
SS0: Single Vector Shadow Register Set bit
1 = Single vector is presented with a shadow register set
0 = Single vector is not presented with a shadow register set
Reserved: Write ‘0’; ignore read
FRZ: Freeze in Debug Exception Mode bit
1 = Freeze operation when CPU is in Debug Exception mode
0 = Continue operation even when CPU is in Debug Exception mode
Note: FRZ is writable in Debug Exception mode only, it is forced to ‘0’ in normal mode.
Reserved: Write ‘0’; ignore read
MVEC: Multi-Vector Configuration bit
1 = Interrupt controller configured for Multi-Vectored mode
0 = Interrupt controller configured for Single Vectored mode
Reserved: Write ‘0’; ignore read
TPC<2:0>: Temporal Proximity Control bits
111 = Interrupt of group priority 7 or lower starts the IP timer
110 = Interrupt of group priority 6 or lower starts the IP timer
101 = Interrupt of group priority 5 or lower starts the IP timer
100 = Interrupt of group priority 4 or lower starts the IP timer
011 = Interrupt of group priority 3 or lower starts the IP timer
010 = Interrupt of group priority 2 or lower starts the IP timer
001 = Interrupt of group priority 1 starts the IP timer
000 = Disables proximity timer
Reserved: Write ‘0’; ignore read
INT4EP: External Interrupt 4 Edge Polarity Control bit
1 = Rising edge
0 = Falling edge
