Nonmaskable interrupts (NMI) can be generated by chip-level registers and the LRESET can be generated by software writing into LPSC registers. LRESET and NMI can also be asserted by device pins or watchdog timers. One NMI pin and one LRESET pin are shared by all CorePacs on the device. The CORESEL[3:0] pins can be configured to select between the CorePacs available as shown in Table 6-34.
