System Integration Module (SIM)
Interrupt Status Register 2
I14–I7 — Interrupt Flags 14–7
Interrupt Status Register 3
Bits 7–2 — Always read 0
I16–I15 — Interrupt Flags 16–15
15.5.2 Reset
All reset sources always have equal and highest priority and cannot be arbitrated.
15.5.3 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.
15.5.4 Status Flag Protection in Break Mode
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 SIM break flag control register (SBFCR).

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