System Integration Module (SIM)
19.5.1.5 Interrupt Status Register 2
IF14–IF8 — Interrupt Flags 14–7
Bit 0 — Always reads 0
19.5.1.6 Interrupt Status Register 3
Bits 7–2 — Always read 0
I16–I15 — Interrupt Flags 16–15
19.5.2 Reset
All reset sources always have equal and highest priority and cannot be arbitrated.
19.5.3 Break Interrupts
The break module can stop normal program flow at a software-programmable break point by asserting its
break interrupt output. See
break state by forcing it to the SWI vector location. Refer to the break interrupt subsection of each module
to see how each module is affected by the break state.
