IF15 — Interrupt Flags
Bit 1–7 — Always read 0
All reset sources always have equal and highest priority and cannot be
arbitrated.
The break module can stop normal program flow at a software
programmable break point by asserting its break interrupt output. (See
Section 17. Break Module
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.
