Bit 0–6 — Always read 0
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
Support.) The SIM puts the CPU into the break state by forcing it to the SWI vector
