14.6.2 Interrupt Status Register 2
IF14–IF7 — Interrupt Flags 14–7
14.6.3 Interrupt Status Register 3
IF16–IF15 — Interrupt Flags 16–15
Bits 7–2 — Always read 0
14.6.4 Reset
All reset sources always have higher priority than interrupts and cannot be arbitrated.
14.6.5 Break Interrupts
The break module can stop normal program flow at a software-programmable break point by asserting its
break interrupt output. See
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.
