System Integration Module (SIM)
Interrupt Status Register 2
I14–I7 — Interrupt Flags 14–7
Interrupt Status Register 3
Bits 7–6 — Always read 0
I16 and I15 — Interrupt Flags 16 and 15
14.5.2 Reset
All reset sources always have equal and highest priority and cannot be arbitrated.
14.5.3 Break Interrupts
The break module can stop normal program flow at a software-programmable break point by asserting
its break interrupt output (see
CPU into the 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.
14.5.4 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).
