Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 31-24 NMIKEY<7:0>: Non-Maskable Interrupt Key bits
When the correct key (0x4E) is written, a software NMI will be generated. The status is indicated by the
GNMI bit (RNMICON<19>).
bit 23-13 Unimplemented: Read as ‘0’
bit 12 MVEC: Multi Vector Configuration bit
1 = Interrupt controller configured for multi vectored mode
0 = Interrupt controller configured for single vectored mode
bit 11 Unimplemented: Read as ‘0’
bit 10-8 TPC<2:0>: Interrupt Proximity Timer Control bits
111 = Interrupts of group priority 7 or lower start the Interrupt Proximity timer
110 = Interrupts of group priority 6 or lower start the Interrupt Proximity timer
101 = Interrupts of group priority 5 or lower start the Interrupt Proximity timer
100 = Interrupts of group priority 4 or lower start the Interrupt Proximity timer
011 = Interrupts of group priority 3 or lower start the Interrupt Proximity timer
010 = Interrupts of group priority 2 or lower start the Interrupt Proximity timer
001 = Interrupts of group priority 1 start the Interrupt Proximity timer
000 = Disables Interrupt Proximity timer
bit 7-5 Unimplemented: Read as ‘0’
bit 4 INT4EP: External Interrupt 4 Edge Polarity Control bit
1 = Rising edge
0 = Falling edge
