Address:
IF14–IF7 — Interrupt Flags 14–7
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 19. 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.
The SIM controls whether status flags contained in other modules can
be cleared during break mode. The user can select whether flags are
protected from being cleared by properly initializing the break clear flag
enable bit (BCFE) in the break flag control register (BFCR).

These flags indicate the presence of interrupt requests from the
sources shown in
1 = Interrupt request present
0 = No interrupt request present
