System Integration Module (SIM)
5.5.2.2 Interrupt Status Register 2
IF7, IF8, IF11 to F14 — Interrupt Flags
Bit 2 and 3 — Always read 0
5.5.2.3 Interrupt Status Register 3
IF15 — Interrupt Flags
Bit 1 to 7 — Always read 0
5.5.3 Reset
All reset sources always have equal and highest priority and cannot be arbitrated.
5.5.4 Break Interrupts
The break module can stop normal program flow at a software-programmable break point by asserting its
break interrupt output. (See
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.
